In _dpu_plane_setup_pixel_ext function instead of dividing just chroma
source resolution once (component 1 and 2), second component is divided
once more because src_w and src_h variable is reused between iterations.
Third component receives wrong source resolution too (from component 2).
To fix this introduce temporary variables for each iteration.
Fixes: dabfdd89eaa9 ("drm/msm/disp/dpu1: add inline rotation support for
sc7280")
