mm/hugetlb.c: avoid double unlock_page() in hugetlb_fault()
Have hugetlb_fault() call unlock_page(page) only if it had previously
called lock_page(page).
Setting CONFIG_DEBUG_VM=y and then running the libhugetlbfs test suite,
resulted in the tripping of VM_BUG_ON(!PageLocked(page)) in
unlock_page() having been called by hugetlb_fault() when page ==
pagecache_page. This patch remedied the problem.
