[PATCH] cp: -Z: fix memory leak edge case

[Pádraig Brady]

From: Bernhard Voelker <m...@bernhard-voelker.de>

src/selinux.c (defaultcon): In edge cases where scontext is
allocated, while tcontext is not, ensure both are deallocated.
Also remove the redundant NULL guard to context_free().
(restorecon_private): Likewise.
