netcardconfig: Run ifdown immediately before configuring the network …

…device

When running netcardconfig the network device is set offline before the
configuration is completed. The network configuration should only be
touched after everything is set.

While at it also removed the sleep phase. The network interface should
be released and down fine after ifdown is completed.
