Revert "player/video: loosen logic checks for adjust_sync"

This reverts commit cb2b579.

This breaks files where the audio starts much later after the video
since mpv reads the first audio packet even if it isn't supposed to
start yet, resulting in the audio_status being STATUS_READY for the
entire time mpv is "waiting" for the first audio packet to be played.
