The REQ flows are concerned that once the handler is called on the new cm_id the ULP can choose to trigger a rdma_destroy_id() concurrently at any time. However, this is not true, while the ULP can call rdma_destroy_id(), it immediately blocks on the handler_mutex which prevents anything harmful from running concurrently. Remove the confusing extra locking and refcounts and make the handler_mutex protecting state during destroy more clear.
