    automation: qemu-smoke-arm64: Silence ifconfig error messages
    
    During the ping test, dom1 tries to assign an ip to eth0 in a loop.
    Before setting up the network interface by dom0, this results in
    printing the following error message several times:
    (XEN) DOM1: ifconfig: SIOCSIFADDR: No such device
    
    Silence this by redirecting stderr/stdout to /dev/null as we do not
    care about the output and we should not pollute the log file.
