Work with tuners that do not support V4L2_CID_AUDIO_VOLUME.

Rajil Saraswat <rajil.s@gmail.com> reported that D-link/Gemtek tuners using
the dsbr100 driver do not support V4L2_CID_AUDIO_VOLUME and therefore fm
failed as follows:

    #fm -d /dev/radio0  -T forever on 106.20
    ioctl VIDIOCGAUDIO: Inappropriate ioctl for device

This commit should fix the problem.
