V4L/DVB (7036): radio: Use video_device_release rather than kfree
The file drivers/media/video/videodev.c defines both video_device_alloc and
video_device_release. These are essentially just kzmalloc and kfree,
respectively, but it seems better to use video_device_release, as done in
the other media files, rather than kfree, in case the implementation some
day changes.
The problem was found using the following semantic match.

Video_device_alloc returns the result of a kzalloc. In this case, the
value is stored in a local variable which is not copied elsewhere before
the point of the error return (video_register_device does not save its
first argument anywhere if it returns a negative value). Thus, a
video_device_release it needed before the error return.
