Commit f67986b0119c04 ("drm/i915/pxp: Promote pxp subsystem to top-level of i915") added PXP initialization to driver probe path, but didn't add a respective PXP cleanup on probe error. That lack of cleanup seems harmless as long as PXP is still unused and idle when a probe failure occurs and error rewind path is entered, but as soon as PXP starts consuming device and driver resources keeping them busy, kernel warnings may be triggered when cleaning up resources provided by memory regions, GGTT, GEM and/or VMA cache from the probe error rewind and/or module unload paths because of missing PXP cleanup. That scenario was observed on attempts to fail the probe and enter the rewind path on injection of now ignored error in device registration path. Fix it.
