r600g/radeonsi: use the correct types (taken from pipe_draw_info)

Note: si_shader.h has also "type" variable that should be changed to
"enum pipe_prim_type", however it triggers a bunch of warnings about
unhandled switches, so due not knowing the correct way to handle them, I
decided to leave it as is.
