uuid updates for 4.13-rc

[Christoph Hellwig]

Hi all,

this series removes fixes a bug in the previous uuid pull request and
removes the the uuid_be type.  I had planned to send the
last patch for -rc1 already but held off to avoid merge conflicts
in linux-next.

In the meantime the thunderbolt code added a few new instances, so
patch once removes them.  I'd like to get this small series into
4.13-rc so that 4.13 is released without the uuid_be type.
