r600g: fix up vs export handling
Certain attributes (position, psize, etc.) don't count as params; they are handled separately by the hw. However, the VS is required to export at least one param and r600_shader_from_tgsi() takes care of adding a dummy export if there is none. Make sure the VS param export count in the SPI properly accounts for this. Note: This is a candidate for the 7.11 branch. Signed-off-by: Alex Deucher <[email protected]>
