Patrick Lerda f3c9ea9b8d st/pbo_compute: fix async->nir memory leak 
This is an issue happening on radeonsi after the commit
6f8e6fb99c "mesa/st: use compute pbo download for readpixels".
This commit enables a new code path which has this memory leak.

For instance, this issue is triggered on radeonsi with
"piglit/bin/glsl-fs-raytrace-bug27060 -auto -fbo":
Too many leaks! Only the first 5000 leaks encountered will be reported.
Indirect leak of 327424 byte(s) in 5582 object(s) allocated from:

======================================================


Source
------

This repository lives at https://gitlab.freedesktop.org/mesa/mesa.
Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.rst
<https://docs.mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support
-------

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `OFTC's #dri-devel
<irc://irc.oftc.net/dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
<https://dri.freedesktop.org/wiki/WhosWho/>`_.

The next best option is to ask your question in an email to the
mailing lists: `mesa-dev\@lists.freedesktop.org
<https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_


Bug reports
-----------

If you think something isn't working properly, please file a bug report
