For users of the CPU-saving bypass mode (e.g. "format rate=bypass"),
this fixes a bug when enqueueing a 44.1kHz immediately after a
48kHz file (or vice-versa).
Note: gapless playback with different rates/channels between
tracks has never been supported with bypass mode enabled.
Bypass only allows opportunistic gapless when sequential tracks
have the same format.
