ALSA: dice: unuse second stream for MIDI conformant data channel for …

…TC Electronic models At present, all of models produced by TC Electronic except for Konnekt Live are supported with hard-coded their stream formats. Studio Konnekt 48 is sore model to support dual streams for both directions. The second stream has no MIDI conformant data channel in its data block. But current implementation transfers the second stream with MIDI conformant data channel. This commit fixes this issue.
