Eric Dumazet 382310d9c8 net/packet: convert po->auxdata to an atomic flag 
[ Upstream commit fd53c297aa ]

po->auxdata can be read while another thread
is changing its value, potentially raising KCSAN splat.

Convert it to PACKET_SOCK_AUXDATA flag.

Fixes: 8dc4194474 ("[PACKET]: Add optional checksum computation for recvmsg")
