net/packet: annotate data race in packet_sendmsg()
[ Upstream commit d1b5bee4c8be01585033be9b3a8878789285285f ]
There is a known race in packet_sendmsg(), addressed
in commit 32d3182cd2cd ("net/packet: fix race in tpacket_snd()")
Now we have data_race(), we can use it to avoid a future KCSAN warning,
as syzbot loves stressing af_packet sockets :)
