net: add {READ|WRITE}_ONCE() annotations on ->rskq_accept_head
[ Upstream commit 60b173ca3d1cd1782bd0096dc17298ec242f6fb1 ]
reqsk_queue_empty() is called from inet_csk_listen_poll() while
other cpus might write ->rskq_accept_head value.
Use {READ|WRITE}_ONCE() to avoid compiler tricks
and potential KCSAN splats.
Fixes: fff1f3001cc5 ("tcp: add a spinlock to protect struct request_sock_queue")
