mm: move pagevec stripping to save unlock-relock
In shrink_active_list() after the deactivation loop, we strip buffer heads
from the potentially remaining pages in the pagevec.
Currently, this drops the zone's lru lock for stripping, only to reacquire
it again afterwards to update statistics.
It is not necessary to strip the pages before updating the stats, so move
the whole thing out of the protected region and save the extra locking.
