mm: add comments to do_mmap(), mmap_region() and vm_mmap()
It isn't always entirely clear to users the difference between do_mmap(),
mmap_region() and vm_mmap(), so add comments to clarify what's going on in
each.
This is compounded by the fact that we actually allow callers external to
mm to invoke both do_mmap() and mmap_region() (!), the latter of which is
really strictly speaking an internal memory mapping implementation detail.
