#8466: VM caches aren't resized in some cases when cutting areas

-----------------------------+------------------------------
In some cases, if an area is partially mapped over (using mmap with
MAP_FIXED, for example) the cache is not resized or split in two,
resulting in memory being leaked for the overlapping region.
See the TODOs in `cut_area()`: http://cgit.haiku-
