For a few reasons. 1: In the (current) common case, these conditionals are never true. All we're doing by checking them is slowing down MakeCurrent. The server does these checks already anyway.
2: GLX >= 3.0 contexts may legally be made current without a bound framebuffer. This does not fix piglit/glx-create-context-current-no-framebuffer, but is a prerequisite for fixing it.
