rcu/nocb: Cancel nocb_timer upon nocb_gp wakeup

Browse source

When waking up in nocb_gp_wait(), there is no need to keep the nocb_timer
around because this function will traverse the whole rdp list. Any
update performed before the timer was armed will now be visible after
the ->nocb_gp_lock acquire.
