In Rdma::AsynchIO::stop():

- make sure we stop the underlying handle immediately whether or not
  we do the stopped callback now or have to defer it.

In qpid::client::RdmaConnector:
- make sure that the shutdown handler is called under all circumstances.
- make sure that the destructor doesn't delete the aio if it is
  already deleted
