md: notify userspace on 'stop' events
This additional notification to 'array_state' is needed to allow the
monitor application to learn about stop events via sysfs. The
sysfs_notify("sync_action") call that comes at the end of do_md_stop()
(via md_new_event) is insufficient since the 'sync_action' attribute has
been removed by this point.
(Seems like a sysfs-notify-on-removal patch is a better fix. Currently
removal updates the event count but does not wake up waiters)
