[Intel-gfx] [PATCH] drm/i915/display: Fix a use-after-free when intel_edp_init_connector fails

We enable the DP aux channel during probe, but may free the connector soon afterwards. Ensure the DP aux display power put is completed before everything is freed, to prevent a use-after-free in icl_aux_pw_to_phy(), called from icl_combo_phy_aux_power_well_disable. Signed-off-by: Maarten Lankhorst
