    Revert "Retry pipequeries on a transient EADDRINUSE in the pipelined test"

    This reverts commit b9cf877277d37db7148a917581a57c7702a35b33.

    The EADDRINUSE came from libuv setting SO_REUSEADDR on the port-0
    bind done by netmgr, a path the Python pipequeries no longer takes,
    so the retry loop is dead weight.
