commit dbd71905ba3183e53bcc699813f6061779001c62

obj_list_get_obj() uses a mutex lock to exclusively access to list.
And the lock is released in function obj_list_put(). Usage of this
couple of functions in the following code path cause deadlock.
  --------
  obj_context_transport_close
      obj_list_get_obj
      secret_PerformAuth_OIAP
          obj_context_get_tcs_api
              obj_list_get_obj
              ...
              obj_list_put
          Transport_OIAP
              obj_context_transport_init
                  obj_list_get_obj
                  ...
                  obj_list_put
      RPC_ReleaseTransportSigned
      obj_list_put
  --------

Also fix a potential hung situation, that authorization session didn't been
released even if establish transport session failed. And retrying will
takes up more authorization sessions, until the thread being forced waiting.
