mm/rmap: parameterise anon_vma_interval_tree_*() by anon_vma
Similar to what we did with mapping_rmap_tree*(), let's declare
anon_vma_interval_tree*() in terms of anon_vma rather than rb_root_cached.
In each case the rb tree referenced is &anon_vma->rb_root, so just pass
anon_vma and the functions can figure this out themselves.
Also update the VMA userland tests to reflect the change.
No functional change intended.
