[PATCH 004 of 9] md: Tidy up device-change notification when an md array is stopped

[NeilBrown <neilb@suse.de>]

An md array can be stopped leaving all the setting still in place,
or it can torn down and destroyed.
set_capacity and other change notifications only happen in the latter
case, but should happen in both.
