[PATCH v4 21/21] mm/mmap: Drop incorrect comment from vms_gather_munmap_vmas()

[Liam R. Howlett]

From: "Liam R. Howlett" <Liam.Howlett@xxxxxxxxxx>

The comment has been outdated since 6b73cff239e52 ("mm: change munmap
splitting order and move_vma()").  The move_vma() was altered to fix the
fragile state of the accounting since then.
