avcodec/aacdec_fixed: Fix preparation for resampler
2nd channel makes sense only for CPE type. Skip 2nd channel in preparation for resampler (in spectral_to _sample()) depending on block type. Fixes fate failure with clang ftrapv. Signed-off-by: Nedeljko Babic <nedeljko.babic@imgtec.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
