From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
If intel_crtc_disable_noatomic() were to ever get called during resume
e'd end up deadlocking since resume has its own acqcuire_ctx but
intel_crtc_disable_noatomic() still tries to use the
mode_config.acquire_ctx. Pass down the correct acquire ctx from the top.
