If the FEC driver is enabled, but the ethernet device was never opened due to booting from another source the wait for graceful transmit stop will always fail. This introduces an unnecessary boot delay and prints a distracting warning. As there is no point in trying to shut down the FEC if it was never started, just skip all of fec_halt in that case.
