usb: chipidea: udc: check request status before setting device address

commit e89ab8ef46a9e93094223cccc7ee4d18fa2212f6 upstream.

The complete() function may be called even though request is not
completed. In this case, it's necessary to check request status so
as not to set device address wrongly.
