Fix plane_strip_copy_rop() to use correct color depth when processing the plane.
Temporarily change mdev->color_info.depth to mdev->planes[plane].depth
so that things work when we process the plane. E.g. this fixes bug where
mem_gray8_rgb24_strip_copy_rop() was overwriting into the line_ptrs[] array.
Fixes segv in:
