A client may not want to use the back channel on a transport it sent
CREATE_SESSION on, in which case it clears SESSION4_BACK_CHAN.
However, cl_cb_addr should be populated anyway, to be used if the
client binds other connections to this session. If cl_cb_addr is
not initialized, rpc_create() fails when the server attempts to
set up a back channel on such secondary transports.
