Here is a reason why we hold tcontext, even if it is not valid.
The hash key of avc_cache is combination of scontext, tcontext and tclass.
Thus, if we replaced an invalid
tcontext by unlabeled context, it would always make cache mishit and
performance loss.
I see that now, thanks.
I have no further comments, and I think that the patch in it's current
status is ready for committer.
