commit c150cf25f1aa5f034baa08360d5be9b8b532b7cb

Second part of fix for bug #7159 - client rpc_transport doesn't cope with bad server data returns.
If server returns zero on a NP read. Report pipe broken.
Prevents client from looping if it thinks there should be
more data.

commit 0223d59ea950c8180047fd5de6c85f92c4e37ad2

First part of fix for bug #7159 - client rpc_transport doesn't cope with bad server data returns.
Ensure that subreq is *always* talloc_free'd in the _done
function, as it has an event timeout attached. If the
read requests look longer than the cli->timeout, then
the timeout fn is called with already freed data.
Jeremy.
