cdrom: handle TOC
This patch should fix TOC handling for cdroms that can not play audio. It extends commit af744e3294d09d706c4eae26cffaaa68a8d40337 ("cdrom: don't check CDC_PLAY_AUDIO in cdrom_count_tracks()") with a safety check and non-audio ioctls support. Since CDC_PLAY_AUDIO flag was used not only to check ability to play audio but also to ensure that audio_ioctl was not NULL, all TOC-related operations had to use it. As far as I understand, now audio_ioctl is never NULL, so a sanity check during device registration should be sufficient. It was tested on Optiarc AD7203A device, that has no ability to play audio.
