Fair enough. I thought also maybe we can keep this purely internal to namei.c,
but it turns out there is one user that I missed in fs/smb/server/vfs.c, so that
one has to be converted still as well.

I mean if we are going to use a separate type for this might as well clean up
the semantics a bit. But I would be fine with keeping LAST_XXX as well.
