r600g: Use virtual address for PIPE_QUERY_SO* in r600_emit_query_end

Virtual address is used for PIPE_QUERY_SO* queries in
r600_emit_query_begin, but not in r600_emit_query_end.

This will trigger a GPU fault when one of those queries is
made and virtual address is enabled.

Note: this is a candidate for the 9.1 branch
