[PATCH 1/2] scsi: smartpqi: use shost_to_hba() in pqi_scan_finished()

[Martin Wilck <martin.wilck@suse.com>]

shost_to_hba() is used everywhere except to obtain pqi_ctrl_info
from shosti, except in pqi_scan_finished(), where shost_priv() is used.
This causes one pointer dereference to be missed, as shost->hostdata
is a pointer in smartpqi. Fix it.
