r600g: fix calculation for gpr allocation

Browse source 
I've been chasing a geom shader hang on rv635 since I wrote
r600 geom code, and finally I hacked some values from fglrx
in and I could run texelfetch without failures.

This is totally my fault as well, maths fail 101.

This makes geom shaders on r600 not fail heavily.
