this breaks request_channel_layout

example:
./ffmpeg -i dts/lotr_5.1_768.dts test.wav

Input #0, dts, from '/home/michael/videos/dts/lotr_5.1_768.dts':
  Duration: 00:02:05.18, start: 0.000000, bitrate: 768 kb/s
    Stream #0:0: Audio: dts (DTS-ES), 48000 Hz, 6.1, fltp, 768 kb/s


vs.
./ffmpeg -request_channel_layout 3 -i dts/lotr_5.1_768.dts test-req3.wav

Input #0, dts, from '/home/michael/videos/dts/lotr_5.1_768.dts':
  Duration: 00:02:05.18, start: 0.000000, bitrate: 768 kb/s
    Stream #0:0: Audio: dts (DTS), 48000 Hz, 5.1(side), fltp, 768 kb/s

vs.
./ffmpeg-ref -request_channel_layout 3 -i dts/lotr_5.1_768.dts test-ref-req3.wav

Input #0, dts, from '/home/michael/videos/dts/lotr_5.1_768.dts':
  Duration: 00:02:05.18, start: 0.000000, bitrate: 768 kb/s
    Stream #0:0: Audio: dts (DTS-ES), 48000 Hz, stereo, fltp, 768 kb/s


previously it resulted in 2 channels now it produces 5.1 when
requesting stereo
