    net: devlink: introduce "unregistering" mark and use it during devlinks iteration
    
    Add new mark called "unregistering" to be set at the beginning of
    devlink_unregister() function. Check this mark during devlinks
    iteration in order to prevent getting a reference of devlink which is
    being currently unregistered.
