Enable NEED_NETDEV for vendor command support.

The Vendor command needs to have the NEED_NETDEV internal flag set
for the corresponding vendor_cmd function to initialize correctly
and call the vendor subcommand specific doit function.

nl80211: nl80211hdr_put() doesn't return an ERR_PTR

There are a few places which check nl80211hdr_put() for an ERR_PTR
but actually it returns NULL on error and never error values.  In
nl80211_testmode_dump() the return wasn't checked at all so I have
added one.

nl80211: fix error path in nl80211_get_key()

Coverity pointed out that in the (practically impossible)
error case we leak the message - fix this.
