Jens Axboe 7c8a3554c6 writeback: ensure that WB_SYNC_NONE writeback with sb pinned is sync
Even if the writeout itself isn't a data integrity operation, we need
to ensure that the caller doesn't drop the sb umount sem before we
have actually done the writeback.

This is a fixup for commit e913fc82.
