[PATCH] md: change ONLINE/OFFLINE events to a single CHANGE event

It turns out that CHANGE is preferred to ONLINE/OFFLINE for various reasons
(not least of which being that udev understands it already).

So remove the recently added KOBJ_OFFLINE (no-one is likely to care anyway)
and change the ONLINE to a CHANGE event
