That's okay. On rmmod, as the low level device (ATA) goes away first
just as in hot unplug, sd gets notified *after* the device is gone but
sd still tries to clean up and issues the commands which are properly
rejected by the SCSI midlayer as the device is marked offline already,
so nothing to worry about there.
