virtual-surround: check if resampled memblock is not equal to input

Browse source 
Since commit e32a408b3c, we silence the
input memblock in order to give the resampler enough input samples, if
necessary.
But if there is no need to resample the hrir, the resampled memblock is
actually the same as the input memblock. Thus, we have to make sure that
we do not silence it in this case.
