[PATCH] remove VM_DONTCOPY bogosities

Now that it's madvisable, remove two pieces of VM_DONTCOPY bogosity:

1. There was and is no logical reason why VM_DONTCOPY should be in the
   list of flags which forbid vma merging (and those drivers which set
   it are also setting VM_IO, which itself forbids the merge).

2. It's hard to understand the purpose of the VM_HUGETLB, VM_DONTCOPY
   block in vm_stat_account: but never mind, it's under CONFIG_HUGETLB,
   which (unlike CONFIG_HUGETLB_PAGE or CONFIG_HUGETLBFS) has never been
   defined.
