V4L/DVB (11734): remove hw reset of MPEG encoder when lost/found seq.

When we capture signal from composite input offen lost and found syncro
sequence. In this case the MPEG coder hardware reset after each
lost/found event. The image has a lot of artefactes. This patch remove
hardware reset of MPEG encoder.

This is patch from our customer. I checked this.

With my best regards, Dmitry.
