    rpc.tlsservd: Check for a tls syscall failure.
    
    Although the tls syscall to set up the upcall should
    not normally fail, the daemon should check for such
    a failure.  This patch adds a check for that failure.
    
    (cherry picked from commit ab3c59a107c56d4304b6ba2c36116b87a0122b4f)
