V4L/DVB (3277): Use default tuner_params if desired_type not available

Browse Source 
If a given tuner definition contains more than one tuner_params array members,
it will try to select the appropriate tuner_params based on the video standard
in use. If there is no tuner_params defined for the current video standard, it
will select the default, tuner_params[0]
