net: add {READ|WRITE}_ONCE() annotations on ->rskq_accept_head

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: c158132c33fe ("tcp: add a spinlock to protect struct request_sock_queue")
