mesa: use signed temporary variable to store _ColorDrawBufferIndexes
_ColorDrawBufferIndexes is defined as GLint* and using a GLuint* will result in the first part of the conditional to be evaluated to true always. Unintentionally introduced by the following commit, this will result in a driver segfault if one is using an old version of the piglit test bin/clearbuffer-mixed-format -auto -fbo commit 03d848ea Author: Marek Olšák <marek.olsak@amd.com> Date: Wed Dec 4 00:27:20 2013 +0100 mesa: fix interpretation of glClearBuffer(drawbuffer) This corresponding piglit tests supported this incorrect behavior instead of pointing at it.
