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.
