cdrom: track if a cdrom_device_info was opened for data

Set a flag when a cdrom_device_info is opened for writing, instead of
trying to figure out this at release time.  This will allow to eventually
remove the mode argument to the ->release block_device_operation as
nothing but the CDROM drivers uses that argument.
