Eric Dumazet 5a9071a760 tcp: annotate data-races around icsk->icsk_pending ...

icsk->icsk_pending can be read locklessly already.

Following patch in the series will add another lockless read.

Add smp_load_acquire() and smp_store_release() annotations
because following patch will add a test in tcp_write_timer(),
and READ_ONCE()/WRITE_ONCE() alone would possibly lead to races.
