lavc/avfft: fix RDFT wrapper stride
Per the lavu/tx docs:
> * For forward transforms (R2C), stride must be the spacing between two
> * samples in bytes. For inverse transforms, the stride must be set
> * to the spacing between two complex values in bytes.
The code did the reverse.
The stride parameter is currently not respected for RDFT transforms,
but has to be correct, for a potential future change.
