cdrom: respect device capabilities during opening action

[ Upstream commit 366ba7c71ef77c08d06b18ad61b26e2df7352338 ]

Reading the TOC only works if the device can play audio, otherwise
these commands fail (and possibly bring the device to an unhealthy
state.)

Similarly, cdrom_mmc3_profile() should only be called if the device
supports generic packet commands.
