    pcscd: do not write to a closed file handle
    
    " In case of receiving a signal to terminate after init has been
    completed, at_exit() is called and tries to write to a closed pipe.
    
    This patch simply set pipe to -1 in order to invalidate it after
    closing.  Pipe value checks are already present in the code. "
