    glusterd: don't queue attach reqs before connecting

    This was causing USS tests to fail.  The underlying problem here is
    that if we try to queue the attach request too soon after starting a
    brick process then the socket code will get an error trying to write
    to the still-unconnected socket.  Its response is to shut down the
    socket, which causes the queued attach requests to be force-unwound.
    There's nothing to retry them, so they effectively never happen and
    those bricks (second and succeeding for a snapshot) never become
    available.

    We *do* have a retry loop for attach requests, but currently break out
    as soon as a request is queued - not actually sent.  The fix is to
    modify that loop so it will wait some more if the rpc connection isn't
    even complete yet.  Now we break out only when we have a completed
    connection *and* a queued request.
