Subject: [PATCH 1/7] usb: dwc3: core: fix dwc3_probe() to not do put_sync when get_sync fails

dwc3_probe() does pm_runtime_put_sync() in its err1 handling when
pm_runtime_get_sync() fails.  Move the pm_runtime_put_sync() under
err2 instead as it is used in error paths after pm_runtime_get_sync()
succeeds.
