   aacdec_usac: skip FD-specific decoding for LPD channels
   `spectrum_decode` currently executes Frequency Domain (FD) decoding steps
   for all channels, regardless of their `core_mode`. When a channel is in
   Linear Prediction Domain (LPD) mode (`core_mode == 1`), FD-specific
   parameters such as scalefactor offsets (`sfo`) and individual channel
   stream (`ics`) information are not parsed.
   
   This causes a global-buffer-overflow in `dequant_scalefactors`. Because
   `spectrum_scale` is called on LPD channels, it uses stale or
   uninitialized `sfo` values to index `ff_aac_pow2sf_tab`. In the reported
   crash, a stale `sfo` value of 240 resulted in an index of 440
   (240 + POW_SF2_ZERO), exceeding the table's size of 428.
   
   Fix this by ensuring `spectrum_scale` and `imdct_and_windowing` are only
   called for channels where `core_mode == 0` (FD).

   avcodec/aac/aacdec_usac_mps212: Off-by-one bounds check in ff_aac_ec_data_deci()
   Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
   
   No testcase, the check seems redundant
