    pseries/llan: call init when ioctl sets interface UP

    This should fix dhcp on an unitialized interface.  This solution was
    found while comparing against another driver, SIOCSIFFLAGS is used by
    dhclient to force the interface up before it has an IP address.
    However, all setup work is done in llan_init(), so the interface would
    not be enabled if configured via only the SIOCSIFFLAGS ioctl.  By
    running llan_init() when the interface is forced up via SIOCSIFFLAGS,
    the interface is initialized properly.
