Parthasarathy Bhuvaragan 4de13d7ed6 tipc: fix nullptr crash during subscription cancel ... commit 4d5cfcba2f ('tipc: fix connection abort during subscription cancel'), removes the check for a valid subscription before calling tipc_nametbl_subscribe(). This will lead to a nullptr exception when we process a subscription cancel request. For a cancel request, a null subscription is passed to tipc_nametbl_subscribe() resulting in exception. In this commit, we call tipc_nametbl_subscribe() only for a valid subscription.
