Dmitry Baryshkov 2dde2aadae drm/msm/dpu: don't set crtc_state->mode_changed from atomic_check() ...

The MSM driver uses drm_atomic_helper_check() which mandates that none
of the atomic_check() callbacks toggles crtc_state->mode_changed.
Perform corresponding check before calling the drm_atomic_helper_check()
function.
