    ifconfig: print interface name on SIOCIFCREATE2 error
    
    We have repeatedly gotten reports of unclassified SIOCIFCREATE2 errors
    (usually "Device not configured").  This can happen if there is
    configuration for interfaces in rc.conf which do not (yet) exist and
    we try to configure.  I can, e.g., provoke this by configuring wlan
    interfaces with their physical interface not installed.
    In order to cut support (guesswork) down print the name of the
    interface to be configured with the error message.
    Hopefully this will help us in the future to improve other configuration
    or driver problems.
