    usbnet: Fix ordering of actions in usbnet_stop.

    Make sure all software activity is quiescent (callouts and tasks,
    including ifmedia and mii callbacks -- anything that might trigger
    register access) before asking the driver to stop the hardware.  This
    way, the driver uno_stop routine is guaranteed exclusive access to
    the registers.

    This will also enable us to simplify the callouts and tasks so they
    don't have to check the software state -- to be done in a separate
    commit.
