hugetlbfs: hugetlb_fault_mutex_hash() cleanup
commit 552546366a30d88bd1d6f5efe848b2ab50fd57e5 upstream.
A new clang diagnostic (-Wsizeof-array-div) warns about the calculation
to determine the number of u32's in an array of unsigned longs.
Suppress warning by adding parentheses.
While looking at the above issue, noticed that the 'address' parameter
to hugetlb_fault_mutex_hash is no longer used. So, remove it from the
definition and all callers.
No functional change.
