st/mesa: fix renderbuffer validation bug

After we attach a new renderbuffer in this function we need to make
sure Mesa's update_framebuffer() gets called.

Fixes crash in WebGL conformance/textures/texture-attachment-formats.html,
but the test still fails for other reasons.

Fixes http://bugs.freedesktop.org/show_bug.cgi?id=53316

Note: This is a candidate for the 8.0 branch.
