usb: cdns3: fix static checker warning.
The patch c450e48eb570: "usb: cdns3: add power lost support for
system resume" from Feb 18, 2021, leads to the following static
checker warning:
drivers/usb/cdns3/core.c:551 cdns_resume()
error: uninitialized symbol 'ret'.
drivers/usb/cdns3/core.c
544
545 if (!role_changed) {
546 if (cdns->role == USB_ROLE_HOST)
547 ret = cdns_drd_host_on(cdns);
548 else if (cdns->role == USB_ROLE_DEVICE)
549 ret = cdns_drd_gadget_on(cdns);
"ret" is uninitialized at else branch.
