[SCSI] hpsa: do not consider firmware revision when looking for device changes.
The firmware may have been updated, in which case, it's the same device, and in that case, we do not want to remove and add the device, we want to let it continue as is. Signed-off-by: Stephen M. Cameron <scameron@beardog.cce.hp.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
