i965: Mark all EGLimages as non-coherent.
EGLimages are shared with external users, and we don't know what they're going to do with them. They might scan them out. They might access them in a way that doesn't work with our explicit clflushing. It's safest to simply mark them non-coherent. Chris Wilson caught this problem and wrote a similar (though less aggressive) patch to solve it; the miptree code has since undergone a lot of refactoring so I had to rewrite it.
