usb: dwc2: dwc2_vbus_supply_init: fix error check
devm_regulator_get_optional returns -ENODEV if the regulator isn't
there, so if that's the case we have to make sure not to leave -ENODEV
in the regulator pointer.
Also, make sure we return 0 in that case, but correctly propagate any
other errors. Also propagate the error from _dwc2_hcd_start.
Fixes: 531ef5ebea96 ("usb: dwc2: add support for host mode external vbus supply")
