radeon: avoid rounding errors in texture coords for textured xv on EG+
make sure the division is done with floats, otherwise the coordinate
can be wrong up to 1 texel.
Particularly visible with clipping and small source scaled up (since one
texel can be a shift of several pixels) but could be seen even unscaled.
Should provide more accurate coords without clipping too depending on the
scale factor probably.
This is a straight port of 688c8a54a00b01e73a11970ad2abe858f8c7c5c4
when I apparently forgot the eg code...
