adpcm: Fix trellis encoding of IMA QT
This was broken in 095be4fb - samples+ch (for the previous non-planar case) equals &samples_p[ch][0]. The confusion probably stemmed from the IMA WAV case where it originally was &samples[avctx->channels + ch], which was correctly changed into &samples_p[ch][1]. Fixes part of Ticket3701 Signed-off-by: Michael Niedermayer <michaelni@gmx.at> (cherry picked from commit a32765c4252eb106a2ade543026ef6f59e699bfa)
