ext4: Move page unlocking out of mpage_submit_page()

Browse source

Move page unlocking during page writeback out of mpage_submit_page()
into the callers. This will allow writeback in data=journal mode to keep
the page locked for a bit longer. Since page unlocking it tightly
connected to increment of mpd->first_page (as that determines cleanup of
locked but unwritten pages), move page unlocking as well as
mpd->first_page handling into a helper function.
