drm/amdgpu: revert to old status lock handling v3
It turned out that protecting the status of each bo_va with a
spinlock was just hiding problems instead of solving them.
Revert the whole approach, add a separate stats_lock and lockdep
assertions that the correct reservation lock is held all over the place.
This not only allows for better checks if a state transition is properly
protected by a lock, but also switching back to using list macros to
iterate over the state of lists protected by the dma_resv lock of the
root PD.
v2: re-add missing check
v3: split into two patches
