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.
