mm: Use maple tree operations for find_vma_intersection() and find_vma()

Move find_vma_intersection() to mmap.c and change implementation to
maple tree.

When searching for a vma within a range, it is easier to use the maple
tree interface.  This means the find_vma() call changes to a special
case of the find_vma_intersection().

Exported for kvm module.
