md: call md_update_sb even for 'external' metadata arrays.
Now that we depend on md_update_sb to clear variable bits in
mddev->flags (rather than trying not to set them) it is important to
always call md_update_sb when appropriate.
md_check_recovery has this job but explicitly avoids it for ->external
metadata arrays. This is not longer appropraite, or needed.
However we do want to avoid taking the mddev lock if only
MD_CHANGE_PENDING is set as that is not cleared by md_update_sb for
external-metadata arrays.
