drm/ttm: flush the fence on the bo after we individualize the reservation object
[ Upstream commit 1bbcf69e42fe7fd49b6f4339c970729d0e343753 ]
As we move the ttm_bo_individualize_resv() upwards, we need flush the
copied fence too. Otherwise the driver keeps waiting for fence.
run&Kill kfdtest, then perf top.
