audio_mix: fix zeroing output channels in certain cases
...
Specifically, when the corresponding input channel exists and its matrix
column is all-zero (which is necessary for zeroing the output), the
matrix column must be removed from the matrix.
This is not done currently, so the mixing code would end up using
uninitialized pointers from stack.

audio_mix: initialize the data pointers to NULL
...
This should make it easier to catch problems where some of those
pointers are used uninitialized, since reading from NULL should always
crash, while random numbers from stack can turn out to be valid
pointers, so random memory may be silently overwritten.
