etm_audio.c: fix off-by-one error in auw of FIR coefficients The implementation of auw operation for UL or DL FIR upload had this bug: the number of 16-bit shortwords copied into the RVF-allocated temporary buffer was one too many, causing memory corruption errors. The present change fixes this bug.
