gpu: ipu-v3: image-convert: Fix input bytesperline width/height align
[ Upstream commit ff391ecd65a1b8324c49046c3db98d9c8ab29af9 ]
The output width and height alignment values were being used in the
input bytesperline calculation. Fix by separating local vars w_align
and h_align into w_align_in, h_align_in, w_align_out, and h_align_out.

adjustment")
