USB: dwc3: clean up phy init error handling
While there likely are no platforms out there that mix generic and
legacy PHYs the driver should still be able to handle that, if only for
consistency reasons.
Add the missing calls to shutdown any legacy PHYs if generic PHY
initialisation fails.
Note that we continue to happily ignore potential errors from the legacy
PHY callbacks...
