audio: fix obscure audio resync failure with timelines
Somehow, there was a larger misunderstanding in the code: ao_buffer does not need to be preserved over audio reinit for proper support of gapless audio. The actual AO internal buffer takes care of this. In fact, preserving ao_buffer just breaks audio resync. In the ordered chapter case, end_pts is used, which means not all audio data in the buffer is played, thus some data is left over when audio decoding resumes on the next segment. This triggers some code that aborts resync if there's "audio decoded" (ao_buffer contains something), but no PTS is known (nothing was actually decoded yet). Simplify, and always bind the output buffer to the decoder. CC: @mpv-player/stable (maybe)
