drm/i915: Hold struct_mutex for per-file stats in debugfs/i915_gem_object
As we walk the obj->vma_list in per_file_stats(), we need to hold
struct_mutex to prevent alteration of that list.
Fixes: 1d2ac403ae3b ("drm: Protect dev->filelist with its own mutex")
Fixes: c84455b4bacc ("drm/i915: Move debug only per-request pid tracking from request to ctx")
