hugetlbfs: do not call user_shm_lock() for MAP_HUGETLB fix
Commit 6bfde05bf5c ("hugetlbfs: allow the creation of files suitable for
MAP_PRIVATE on the vfs internal mount") altered can_do_hugetlb_shm() to
check if a file is being created for shared memory or mmap(). If this
returns false, we then unconditionally call user_shm_lock() triggering a
warning. This block should never be entered for MAP_HUGETLB. This
patch partially reverts the problem and fixes the check.
