[Mesa-stable] [PATCH 1/8] mesa: Add missing checks for GL_TEXTURE_CUBE_MAP_ARRAY

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

That enum requires GL_ARB_texture_cube_map_array, and it is only
available on desktop GL.  It looks like this has been an un-noticed
issue since GL_ARB_texture_cube_map_array support was added in commit
e0e7e295.

Since this just adds a missing error check, it's arguable that this
should not be included in stable branches.  Opinions?
