Daniel P. Berrange b4633113fc Fix race condition in abort of stream 
If a stream gets a server initiated abort, the client may still
send an abort request before it receives the server side abort.
This causes the server to send back another abort for the
stream. Since the protocol defines that abort is the last thing
to be sent, the client gets confused by this second abort from
the server. If the stream is already shutdown, just drop any
client requested abort, rather than sending back another message.
This fixes the regression from previous versions.

Tested as follows

In one virsh session

  virsh # start foo
  virsh # console foo

In other virsh session

  virsh # destroy foo

The first virsh session should be able to continue issuing
commands without error. Prior to this patch it saw

  virsh # list
  error: Failed to list active domains
  error: An error occurred, but the cause is unknown

  virsh # list
  error: Failed to list active domains
  error: no call waiting for reply with prog 536903814 vers 1 serial 9

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
