r600: fix cayman msaa shading behavior
The functionality was working properly at glMinSampleShading(0.)
and glMinSampleShading(1.). The issue was with the intermediary
values. This change makes this function compatible with the
evergreen setup.

Note: this was one of the few functionalities which were working
properly on evergreen but not on cayman.

Here are the tests fixed:
spec/arb_sample_shading/samplemask 4 all/0.500000 partition: fail pass
spec/arb_sample_shading/samplemask 4/0.500000 partition: fail pass

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

.. code-block:: sh

  $ meson setup build
  $ ninja -C build/
  $ sudo ninja -C build/ install

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.
