    net: nexthop: Initialize NH group ID in resilient NH group notifiers

    The NEXTHOP_EVENT_RES_TABLE_PRE_REPLACE notifier currently keeps the group
    ID unset. That makes it impossible to look up the group for which the
    notifier is intended. This is not an issue at the moment, because the only
    client is netdevsim, and that just so that it veto replacements, which is a
    static property not tied to a particular group. But for any practical use,
    the ID is necessary. Set it.
