    Fix for Quantum LinuxBridge Intf driver plug call

    The current implementation of the plug operation tries to assign an IP
    address to a bridge even if it already has one. The fix is to do this
    only when a new device is created. The check for a new device was
    already being performed however the IP address was being set outside
    that check. That's being corrected here, minor fix.
