rcu: Make synchronize_rcu_expedited() fast path update .expedited_sequence
This commit causes the early boot single-CPU synchronize_rcu_expedited() fastpath to update the rcu_state structure's ->expedited_sequence counter. This will allow the full-state polled grace-period APIs to detect all expedited grace periods without the need to track the special combined polling-only counter, which is another step towards removing the ->rgos_polled field from the rcu_gp_oldstate, thereby reducing its size by one third.
