hpsa: add discovery polling for PT RAID devices.
There are problems with getting configuration change notification
in pass-through RAID environments. So, activate flag
h->discovery_polling when one of these devices is detected in
update_scsi_devices.
After discovery_polling is set, execute a report luns from
rescan_controller_worker (every 30 seconds).
If the data from report_luns is different than last
time (binary compare), execute a full rescan via update_scsi_devices.
