xen/xen-blkback: preq.dev is used without initialized

If call xen_vbd_translate failed, the preq.dev will be not initialized.
Use blkif->vbd.pdevice instead (still better to print relative info).

Note that before commit 01c681d4c70d64cb72142a2823f27c4146a02e63
(xen/blkback: Don't trust the handle from the frontend.)
the value bogus, as it was the guest provided value from req->u.rw.handle
rather than the actual device.

mac80211: always synchronize_net() during station removal

If there are keys left during station removal, then a
synchronize_net() will be done (for each key, I have a
patch to address this for 3.10), otherwise it won't be
done at all which causes issues because the station
could be used for TX while it's being removed from the
driver -- that might confuse the driver.

Fix this by always doing synchronize_net() if no key
was present any more.

cfg80211: fix potential BSS memory leak and update

In the odd case that while updating information from a beacon,
a BSS was found that is part of a hidden group, we drop the
new information. In this case, however, we leak the IE buffer
from the update, and erroneously update the entry's timestamp
so it will never time out. Fix both these issues.

mac80211: fix crash with P2P Device returning action frames

If a P2P Device interface receives an unhandled action
frame, we attempt to return it. This crashes because it
doesn't have a channel context. Fix the crash by using
status->band and properly mark the return frame as an
off-channel frame.

xen/blkback: correctly respond to unknown, non-native requests

If the frontend is using a non-native protocol (e.g., a 64-bit
frontend with a 32-bit backend) and it sent an unrecognized request,
the request was not translated and the response would have the
incorrect ID.  This may cause the frontend driver to behave
incorrectly or crash.

Since the ID field in the request is always in the same place,
regardless of the request type we can get the correct ID and make a
valid response (which will report BLKIF_RSP_EOPNOTSUPP).

This bug affected 64-bit SLES 11 guests when using a 32-bit backend.
This guest does a BLKIF_OP_RESERVED_1 (BLKIF_OP_PACKET in the SLES
source) and would crash in blkif_int() as the ID in the response would
be invalid.

The reverted patch caused opening of ports to fail for rproc_serial.
In probe guest_connected was set to true, but port_fops_open()
fails with -EMFILE if guest_connected already is true.

xen-blkback: fix dispatch_rw_block_io() error path

Commit 7708992 ("xen/blkback: Seperate the bio allocation and the bio
submission") consolidated the pendcnt updates to just a single write,
neglecting the fact that the error path relied on it getting set to 1
up front (such that the decrement in __end_block_io_op() would actually
drop the count to zero, triggering the necessary cleanup actions).

Also remove a misleading and a stale (after said commit) comment.
