Subject[PATCH 3/3] Infiniband: don't use task_struct.tgid in make_cm_node()
The task_struct->tgid field is about to become deprecated, due to
pid namespaces make tasks have many pids, not one. There is one
place using it left to fix in infiniband - the make_cm_node().

This function uses the task tgid just to generate a session id,
so it's perfectly safe to use appropriate wrapper - task_tgid_nr().
