[Intel-gfx] [PATCH] drm/i915/selftests: Mark contexts as lost during freeing of mock device

[Chris Wilson]

We need to unpin the last retired context early in the shutdown sequence
so that its RCU free is done before we try to free the context ida. I
included this in a later patch ("drm/i915: Keep a recent cache of freed
contexts objects for reuse") and so missed that the selftests were broken
in the meantime.
