Re: [PATCH v4 7/9] scsi: Only process PM requests if rpm_status != RPM_ACTIVE

Instead of submitting all SCSI commands submitted with scsi_execute() to a
SCSI device if rpm_status != RPM_ACTIVE, only submit RQF_PM (power
management requests) if rpm_status != RPM_ACTIVE. This patch makes the
SCSI core handle the runtime power management status (rpm_status) as it
should be handled.
