scsi: pm: keep request queue and scsi device runtime status in sync
If scsi device is not runtime suspended while system resumes then
scsi device's runtime PM status gets changed to RPM_ACTIVE (if its
parent status is already set to RPM_ACTIVE) by the scsi system resume
callback. But if the scsi device's runtime PM is managed by block layer
then runtime status of scsi device's request queue might still remain
in RPM_SUSPENDED hence all the new block requests submitted to the
request queue will have to wait until the queue runtime status gets
changed to RPM_ACTIVE which never happens as scsi device status is
already marked RPM_ACTIVE.
Fix this problem by changing the request queue runtime status to
RPM_ACTIVE when scsi device runtime status changes to RPM_ACTIVE.
