Subject: [PATCH] drm/i915/selftests: Mark contexts as lost during freeing of mock device
Git-commit: 56d27666f8fa21835724217b0c67d42b769b5723
Patch-mainline: v4.14-rc1
References: FATE#322643 bsc#1055900

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.
