[ Upstream commit 29e8e659f984be00d75ec5fef4e37c88def72712 ]
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.
