[tipc-discussion] [net 4/5] tipc: advance the time of calling tipc_nametbl_unsubscribe

[Ying X. <yin...@wi...>]

When subscription is inserted into subscriber->subscrp_list, the
subscription is also inserted to name sequence subscriptions list.
Now when subscription is deleted from subscriber->subscrp_list in
tipc_subscrb_subscrp_delete(), it's also a proper time to delete
the subscription from name sequence subscriptions list too.
