<pre>Actually intel_get_tex_sub_image() is called 3 times: 2 times during test
initialization (source datas are float 0 1 0 1 and all floats 66) and once when
checking the results (source data is half red - half green).
Destination addresses for these 3 calls all different.
Modifying test to do Write-Read-Write (instead of Write-Write) solving the
issue.
Write-Write-Write still fails.
P.S. these results are for "fallback" path with intel_gettexsubimage_blorp
returning false.</pre>
