Subject: [PATCH 1/1] ALSA: compress: no need to set metadata before next
	track

The metadata is mainly for MP3 gapless playback, since
the MP3 audio stream does not contain enough information
to enable gapless. Other audio formats do not necessarily
require any additional metadata so we should allow next_track
to be called without any metadata.
