Use _mm_free on memory allocated with _mm_malloc.

Browse Source 
kiss_fft_alloc and kiss_fftr_alloc internally use KISS_FFT_MALLOC to allocate memory, which is defined to _mm_malloc in a SIMD enabled application. Calling free() on memory allocated with _mm_malloc will result in unpredictable behavior. The configuration data allocated with _mm_malloc should be freed with a corresponding _mm_free.
