[SCSI] hpsa: only do device rescan for certain events
Do no rescan on every events -- way too many rescans are
triggered if we don't filter the events. Limit rescans
to be triggered by the following set of events:
* controller state change
* enclosure hot plug
* physical drive state change
* logical drive state change
* redundant controller state change
* accelerated io enabled/disabled
* accelerated io configuration change
