Hangbin Liu ab26f11367 net/packet: fix packet_sock xmit return value checking ...

[ Upstream commit 29e8e659f9 ]

packet_sock xmit could be dev_queue_xmit, which also returns negative
errors. So only checking positive errors is not enough, or userspace
sendmsg may return success while packet is not send out.

Move the net_xmit_errno() assignment in the braces as checkpatch.pl said
do not use assignment in if condition.
