drm/rockchip: vop2: use correct destination rectangle height check

The vop2_plane_atomic_check() function incorrectly checks
drm_rect_width(dest) twice instead of verifying both width and height.
Fix the second condition to use drm_rect_height(dest) so that invalid
destination rectangles with height < 4 are correctly rejected.
