scsi: sd: Rework asynchronous resume support
For some technologies, e.g. an ATA bus, resuming can take multiple
seconds. Waiting for resume to finish can cause a very noticeable delay.
Hence this commit that restores the behavior from before "scsi: core: pm:
Rely on the device driver core for async power management" for most SCSI
devices.
This commit introduces a behavior change: if the START command fails, do
not consider this as a SCSI disk resume failure.
