In most cases, notifications on sockets with NETLINK_LISTEN_ALL_NSID
do not contain NSID in their ancillary data in case the event is local
to the listener.
However, when a self-referential NSID is allocated for a namespace,
every local notification starts sending this ID to the user space.
This is p... | ```diff

If the current skb is not shared, it is re-used directly for all the

socket receiving a message first, then the 'nsid_is_set' will be
set to 'true'. If the nsid is NOT_ASSIGNED for the next socket in
