    Pass extents to radeon_scanout_do_update by value
    
    radeon_scanout_extents_intersect could leave the scanout damage region
    in an invalid state, triggering debugging checks in pixman:
    
    *** BUG ***
    In pixman_region_append_non_o: The expression r->x1 < r->x2 was false
    Set a breakpoint on '_pixman_log_error' to debug
    
    (Ported from amdgpu commit 8af989546907ad9fb491d940e1936d3bfc89276b)
