mm/shmem: update file sealing comments and file checking
In preparation for memfd code restructure, update comments, definitions and function names dealing with file sealing to indicate that tmpfs and hugetlbfs are the supported filesystems. Also, change file pointer checks in memfd_file_seals_ptr to use defined interfaces instead of directly referencing file_operation structs.
