libobs: Don't clear audio on ts jump (seamless loops)

There's technically no need to clear the audio data here, nor is there
any need to try to trick the timestamp in to a different position.  It
can simple just reset the audio timing.

Prevents a possible case where audio data might be deleted when it's not
necessary to delete any.
