scsi: smartpqi: Resolve delay issue with PQI_HZ value
Change PQI_HZ to HZ.
PQI_HZ macro was set to 1000 when HZ value is less than 1000. By default,
PQI_HZ will result into a delay of 10 seconds(for kernel, which has HZ =
100). So in this case when firmware raises an event, rescan worker will be
scheduled after a delay of (10 x PQI_HZ) = 100 seconds instead of 10
seconds.
Also driver uses PQI_HZ at many instances, which might result in some other
issues with respect to delay.
