scsi: sd: Retry START STOP UNIT commands
During system resume, sd_start_stop_device() submits a START STOP UNIT
command to the SCSI device that is being resumed. That command is not
retried in case of a unit attention and hence may fail. An example:
[16575.983359] sd 0:0:0:3: [sdd] Starting disk
[16575.983693] sd 0:0:0:3: [sdd] Start/Stop Unit failed: Result: hostbyte=0x00 driverbyte=DRIVER_OK
[16575.983712] sd 0:0:0:3: [sdd] Sense Key : 0x6
[16575.983730] sd 0:0:0:3: [sdd] ASC=0x29 ASCQ=0x0
[16575.983738] sd 0:0:0:3: PM: dpm_run_callback(): scsi_bus_resume+0x0/0xa0 returns -5
[16575.983783] sd 0:0:0:3: PM: failed to resume async: error -5
Make the SCSI core retry the START STOP UNIT command if the device reports
that it has been powered on or that it has been reset.
