drm/crtc_helper: Reset empty plane state in drm_helper_crtc_mode_set_base()
Transitional drivers might access the NULL pointer plane->state in
drm_helper_crtc_mode_set_base(), which causes NULL pointer dereference.
So, let's reset it before handing it over to those drivers.
commit e4f31ad2b713 ("drm: reset empty state in transitional helpers")
did the same thing for other transitional helpers, but it seems this one
was missed.
