dwc3: google: Fix PM domain leak in dwc3_google_probe()

Browse Source 
When syscon_regmap_lookup_by_phandle_args() fails, the function was
returning directly without cleaning up the power domain initialized
earlier by dwc3_google_pm_domain_init().

Fix by jumping to err_deinit_pdom to properly clean up resources.
