ntfs: support FS_IOC_GETFSUUID
NTFS reads the 64-bit volume serial number from the boot sector but leaves
the superblock UUID unset. As a result, the generic FS_IOC_GETFSUUID
handler returns ENOTTY for files and directories on an NTFS volume.
Register the on-disk little-endian serial number as an eight-byte
filesystem identifier with super_set_uuid(). The generic VFS handler can
then expose the existing volume identifier.
