Uses block layer runtime pm helper functions in
scsi_runtime_suspend/resume.
Remove scsi_autopm_* from sd open/release path and check_events path.
And remove the quiesce call in runtime suspend path, as we know there is
no request to quiesce for the device.

How does this handle ioctl() ?

The ioctl code will allocate a new request and execute it through block
layer API, which involves adding the request to the queue and releasing
it when it is finished.

Thanks,
