[PATCH 1/3] gpu: ipu-v3: image-convert: Fix input bytesperline width/height align

[Steve Longerbeam]

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.

Fixes: d966e23d61a2c ("gpu: ipu-v3: image-convert: fix bytesperline
adjustment")
