scsi: sd: Fix Opal support 

The SCSI core has been modified recently such that it only processes PM
requests if rpm_status != RPM_ACTIVE. Since some Opal requests are
submitted while rpm_status != RPM_ACTIVE, set flag RQF_PM for Opal
requests.

See also https://bugzilla.kernel.org/show_bug.cgi?id=211227.

[mkp: updated sha for PM patch]
