Handle zero channels when allocating for resampler

Browse Source 
When the number of channels was zero, we were calling malloc with a
size of zero.  While defined, this is unusual.  And since we're
initializing the speex resampler as though there were one channel in
this case, we should probably just allocate the space for it.
