    rpc.tlsclntd: 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 3fe0cb6695e062b5474ae957bf1856e85ba890bd)
