drm/amd/display: Reduce frame size in the bouding box for DCN31/316

GCC throw warnings for the function dcn31_update_bw_bounding_box and
dcn316_update_bw_bounding_box due to its frame size that looks like
this:

 error: the frame size of 1936 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

For fixing this issue I dropped an intermadiate variable.
