Subject: [PATCH] [SCSI] scsi_pm: Argument to scsi_device_resume should be scsi_device pointer

The call to scsi_device_resume expects a struct scsi_device pointer.
We should use the to_scsi_device macro here.

Sparse is warning about this:
drivers/scsi/scsi_pm.c:30:5: warning:
	passing argument 1 of ‘scsi_device_resume’
	from incompatible pointer type [enabled by default]
	include/scsi/scsi_device.h:368:13: note:
	expected ‘struct scsi_device *’
	but argument is of type ‘struct device *’
