    rpc.tlsservd.c: Pin max threads at 1 for now

    PR#289734 reports a crash in tcp_use_close() when the rpc.tlsservd
    daemon is being used.  Although I have no, as yet, had time to track
    down/fix the race, it turns out setting rpctls_maxthreads to 1
    avoids the problem.

    This patch pins rpctls_maxthreads to 1 to avoid the problem,
    until there is a proper fix.
