[SCSI] aacraid: handle AIF hotplug events (update)

Received from Mark Salyzyn from Adaptec.

Hotplug sniffs the AIFs (events) from the adapter and if a container
change resulting in the device going offline (container zero), online
(container zero completed) or changing capacity (morph) it will take
actions by calling the appropriate API.
