radv/gfx10: make sure to wait for idle before clearing GDS
Otherwise the next streamout operation will overwrite GDS. This
can be improved by tracking if there is a streamout operation in
flight. Currently the driver unconditionally flushes but that
doesn't matter much as NGG streamout is disabled by default.
