media: ivtv: Access v4l2_fh from file

Browse source

The v4l2_fh associated with an open file handle is now guaranteed
to be available in file->private_data, initialised by v4l2_fh_add().

Access the v4l2_fh, and from there the driver-specific structure,
from the file * in all ioctl handlers.

While at it remove the only left user of fh2id() and remove
the macro completely.
