Subject: [PATCH] mesa/main: correct extension-checks for
 GL_BLACKHOLE_RENDER_INTEL

KHR_blend_equation_advanced_coherent isn't exposed on OpenGL ES 1.x
nor OpenGL versions prior to 30, so we shouldn't allow to query its
enum-states there either.

Fixes: 74ec39f66d5 ("mesa: add INTEL_blackhole_render")
