Chris Wilson 16ee20619f drm/i915: Detect vma reserved for execbuf in evict-for-node 
The vma->exec_list is still the only means we have for both reserving an
object in execbuf, and for constructing the eviction list. So during the
construction of the eviction list, we must treat anything already on the
exec_list as being pinned.

Yes, this sharing of two semantically different lists will be fixed! But
in the meantime, we have the issue that this is tripping up CI since we
started using i915_gem_gtt_reserve_node() + i915_gem_evict_for_node()
from the regular execbuf reservation path in commit 606fec956c
("drm/i915: Prefer random replacement before eviction search"):
