drm: Protect dev->filelist with its own mutex amdgpu gained dev->struct_mutex usage, and that's because it's walking the dev->filelist list. Protect that list with it's own lock to take one more step towards getting rid of struct_mutex usage in drivers once and for all. While doing the conversion I noticed that 2 debugfs files in i915 completely lacked appropriate locking. Fix that up too. v2: don't forget to switch to drm_gem_object_unreference_unlocked.
