lavc/h264dsp: fix R-V V weight_pixels pointer arithmetic

As of 459a1512f13ae1fdd404ff9281b02d225ac70a09,
the code is unrolled to process two rows per iteration.
The output cursor thus needs to be incremented by twice the
stride, which is taken care of with SH1ADD. However the original
ADD from the original implemetation was incorrectly left over.
