    modesetting: use drmmode_bo_import() for rotate_fb
    
    drmmode_shadow_allocate() still uses drmModeAddFB() which may fail if
    the format is not as expected, preventing from using a rotated output.
    
    Change it to use the new function drmmode_bo_import() which takes care
    of calling the drmModeAddFB2() API.
