mm/hugetlb: expose hugetlb fault mutex for use by fallocate

hugetlb page faults are currently synchronized by the table of mutexes
(htlb_fault_mutex_table).  fallocate code will need to synchronize with
the page fault code when it allocates or deletes pages.  Expose
interfaces so that fallocate operations can be synchronized with page
faults.  Minor name changes to be more consistent with other global
hugetlb symbols.
