V4L/DVB (3663): Fix msp3400c wait time and better audio mode fallbacks
- The wait time until the first time the audio mode was detected was
1+5=6 seconds instead of just 1 second (wrong statement order).
msp3400c specific bug.
- Implemented audio mode fallback for msp3400c/d just like the msp3400g
does automatically. E.g. fallback to stereo if no second language exists,
etc.
