I think the first hunk is obviously correct, but I don't think we need
the second one, as the handling of the get_acl() eturn value should do
the right thing.  If you want to optimize it a bit, it might be worth to
move the !IS_POSIXACL check in get_acl to the top of the function,
before checking the cached ACL.
