Jeremy Kerr 9990889be1 net: mctp: put sock on tag allocation failure
We may hold an extra reference on a socket if a tag allocation fails: we
optimistically allocate the sk_key, and take a ref there, but do not
drop if we end up not using the allocated key.

Ensure we're dropping the sock on this failure by doing a proper unref
rather than directly kfree()ing.

Fixes: de8a6b15d9 ("net: mctp: add an explicit reference from a mctp_sk_key to sock")
