r300g: set the correct tiling flags for renderbuffers 

MACRO_SWITCH is applied to samplers but not renderbuffers. This commit
fixes incorrect rendering to large and small mipmaps where the large ones
are macrotiled and the small ones are not and both are emitted
in the same CS.

Note that this is still disabled by default (rework of texture transfers
is next).
