Fix stack corruption happening in aacDecoder_drcExtractAndMap()

In the aacDecoder_drcExtractAndMap() function, self->numThreads
  can be used after having exceeded its intended max value,
  MAX_DRC_THREADS, causing memory to be cleared after the
  threadBs[MAX_DRC_THREADS] array.
The crash is prevented by never using self->numThreads with
  a value equal to or greater than MAX_DRC_THREADS.
A proper fix will be required as there seems to be an issue as
  to which entry in the threadBs array is meant to be initialized
  and used.
