audioconvert: fix input remapping

Browse source 
As currently implemented, input format convert channel remap is no-op.
This is because although the out_datas array is permuted, the original
pointer array is not referred to later on, so the only effect is that
the temporary data array is stored in permuted order.

Fix the permutation by permuting the pointers only for the conversion
step.
