r300g: always put MSAA resources in VRAM 

This along with the latest drm-fixes branch should help with bad performance
of MSAA. Remember: Nx MSAA can't be more than N times slower (where N=2,4,6).

Anyway, I recommend at least 512 MB of VRAM for Full HD 6x MSAA.

NOTE: This is a candidate for the 9.1 branch.
