nfsd: back channel stuck in SEQ4_STATUS_CB_PATH_DOWN
When the back channel enters SEQ4_STATUS_CB_PATH_DOWN state, the client recovers by sending BIND_CONN_TO_SESSION but the server fails to recover the back channel and leaves it as NFSD4_CB_DOWN. Fix by enhancing nfsd4_bind_conn_to_session to probe the back channel by calling nfsd4_probe_callback. Signed-off-by:Dai Ngo <dai.ngo@oracle.com> Signed-off-by:
