If bind is fail such as bind is called after set PACKET_FANOUT
sock option, the dev refcnt will leak.

Signed-off-by: Wei Yongjun <redacted>

The device pointer is stored in ->prot_hook.dev

Therefore, it will be released at the latest in packet_release() or
earlier if another bind() attempt is done on the socket.

There is no leak here as far as I can see.
