mesa: fix GL_COLOR_SUM enum for drivers without ARB_vertex_program
Commit c1397080 (mesa: GL_EXT_secondary_color is not optional) changed CHECK_EXTENSION2(EXT_secondary_color, ARB_vetex_program, cap) to CHECK_EXTENSION(ARB_vertex_program, cap) However CHECK_EXTENSION2 checks that either extension is available, not both. Remove the extension check entirely since the intent was for it to always be enabled. v2: Fix glGet*(GL_COLOR_SUM) too. Suggested by Ian. Signed-off-by:Ilia Mirkin <imirkin@alum.mit.edu> Reviewed-by:
