r6xx/r7xx: remove unnecessary state emit

Makes fast scrolling of web pages in seamonkey slower.

If anyone updates then tests this - it won't show until you do a true cold boot.

That fixes it.

I also found that running glxgears would also fix it - so I guess anyone running a compositing desktop would never have seen it.
