[PATCH 6/6] hugetlb: Remove is_file_hugepages()

[Adam Litke <agl@us.ibm.com>]

Now that they have no users, remove the is_file_hugepages() and
set_file_hugepages() macros.

This unshackles the file_operations structure and permits future interfaces
to hugetlb pages to define their own file_operations, distinct from those
currently used by hugetlbfs.
