datapath: Orphan frags in skb_zerocopy and handle errors

This is the ported version of commit 36d5fe6a with the same name from net-next.
Apart from the small datapath.c changes it adjust the compat layer files as
well. This is the original commit message:

"skb_zerocopy can copy elements of the frags array between skbs, but it doesn't
orphan them. Also, it doesn't handle errors, so this patch takes care of that
as well, and modify the callers accordingly. skb_tx_error() is also added to
the callers so they will signal the failed delivery towards the creator of the
skb."

ofproto/bond: Protect statistics with writelock.

dcf00ba35a0 (ofproto/bond: Implement bond megaflow using recirculation)
allowed bond_entry statistics to be modified while holding a readlock.
This patch modifies bond_entry_account() to get a writelock before
modifying the statistics and adds thread-safety annotations to these
fields and relevant functions.

datapath: Allow each vport to have an array of 'port_id's.

In order to allow handlers directly read upcalls from datapath,
we need to support per-handler netlink socket for each vport in
datapath.  This commit makes this happen.  Also, it is guaranteed
to be backward compatible with previous branch.
