[PATCH] hugetlb: fix/remove uninitialized variable in remove_inode_hugepages

[Mike Kravetz]

Code introduced for the routine remove_inode_hugepages by patch "hugetlb:
handle truncate racing with page faults", incorrectly uses a variable
m_index.  This is a remnant from a previous version of the code when
under development.  Use the correct variable 'index' and remove
'm_index' from the routine.
