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.

Fixes: 4d5cfcba2f ('tipc: fix connection abort during subscription cancel')
