drivers: udc_nrf: handle overwritten Set Address commands

USBD peripheral automatically handles Set Address command which can
lead to state mismatch between USB stack and the host. Keep track of
device address and issue fake Set Address commands on mismatch.

This fixes default vs addressed state mismatch that can occur due to
sufficently high SETUP handling latency. The state mismatch was most
commonly seen as SET CONFIGURATION failure when the enumeration happened
during periods with increased latency.
