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

    mesa: fix interpretation of glClearBuffer(drawbuffer)

    This corresponding piglit tests supported this incorrect behavior instead of
    pointing at it.
