The family of vma_interval_tree_() functions manipulate the

reverse mapping, but are named the 'VMA' interval tree.

VMAs may be mapped by an anon_vma, an address_space, or both. Therefore
calling the mapping interval tree a 'VMA' interval tree is rather
confusing.

This is also inconsistent with the anon_vma_interval_tree_*() functions
which explicitly reference the rmap object to which they pertain.

Rename the vma_interval_tree_*() functions to mapping_rmap_tree_*() to
correct this.

We will rename the anon rmap functions similarly in a subsequent patch.

No functional change intended.

Just curious, why not file_rmap_tree_*()?

One nice part of this renaming is that the length of each function does
not chagne. That makes the patch easy to review.
