Mikhail Chusavitin 966944d6d8 Fix audit hanging on smartpqi SAS HBA scan file write ...

smartpqi uses scsi_transport_sas but does not register a sas_host
object, so /sys/class/sas_host/host14 does not exist and the existing
SAS detection check passes right through. Writing to host14/scan then
calls sas_user_scan which blocks indefinitely on scsi_scan_target's
mutex (confirmed by kernel hung-task traces in the field).

Add a second detection path via /sys/class/scsi_host/hostX/proc_name:
skip hosts whose driver is "smartpqi" or "hpsa" (HPE Smart Array
predecessors that exhibit the same behaviour).
