[transcode] Fix problem for file types where ffmpeg decode returns 0

Browse Source 
It seems ffmpeg/libav reads a file type like Monkey's audio in large
chunks, so that each packet must be passed to the decoder multiple
times. The decoder will return 0 until the packet is completed. This
change makes forked-daapd able to deal with a return value of 0.
