[SCSI] sd: implement START/STOP management
Implement SBC START/STOP management. sdev->mange_start_stop is added. When it's set to one, sd STOPs the device on suspend and shutdown and STARTs it on resume. sdev->manage_start_stop defaults is in sdev instead of scsi_disk cdev to allow ->slave_config() override the default configuration but is exported under scsi_disk sysfs node as sdev->allow_restart is. When manage_start_stop is zero (the default value), this patch doesn't introduce any behavior change.
