commit bedf8bcf6b4f90a6e31add3721a2e71877289381 introduced reference counting
for struct v4l2_device.
In v4l2_device_register() a call to kref_init() initializes reference count to 1,
but in v4l2_device_unregister() there is no corresponding decrement.
End result is that reference count never reaches zero and v4l2_device_release()
is never called, not even on videodev module unload.
Fix this by adding reference counter decrement to v4l2_device_unregister().
