Place the ODD into runtime suspend state as soon as there is nobody

OK, so how is ODD related to the sr driver?

Aaron did not make it clear in this patch description, although it may 
have been mentioned in the overall 0/6 description.  "ODD" stands for 
"Optical Disc Drive" -- in other words, a CD or DVD drive.  Once you 
know this, the relation is clear: sr is the SCSI driver for CD/DVD 
drives.
