drm/vmwgfx: Fix Use-after-free in validation
Nodes stored in the validation duplicates hashtable come from an arena
allocator that is cleared at the end of vmw_execbuf_process. All nodes
are expected to be cleared in vmw_validation_drop_ht but this node escaped
because its resource was destroyed prematurely.
Fixes: 64ad2abfe9a6 ("drm/vmwgfx: Adapt validation code for reference-free lookups")
