nfsd4: CREATE_SESSION should update backchannel immediately
nfsd4_probe_callback kicks off some work that will eventually run
nfsd4_process_cb_update and update the session flags. In theory we
could process a following SEQUENCE call before that update happens
resulting in flags that don't accurately represent, for example, the
lack of a backchannel.
