[PATCH 13/14] md: move funcs from pers->resize to update_size

[Guoqing Jiang <gqjiang@xxxxxxxx>]

raid1_resize and raid5_resize should also check the
mddev->queue if run underneath dm-raid.

And both set_capacity and revalidate_disk are used in
pers->resize such as raid1, raid10 and raid5. So
move them from personality file to common code.
