hugetlbfs: hugetlb_vmtruncate_list() needs to take a range to delete

Orabug: 21652814

fallocate hole punch will want to unmap a specific range of pages.  Modify
the existing hugetlb_vmtruncate_list() routine to take a start/end range.
If end is 0, this indicates all pages after start should be unmapped.
This is the same as the existing truncate functionality.  Modify existing
callers to add 0 as end of range.

Since the routine will be used in hole punch as well as truncate
operations, it is more appropriately renamed to hugetlb_vmdelete_list().
