[PATCH 1/1] cr: uts: don't deref h after freeing

["Serge E. Hallyn" <serue-r/Jw6+rmf7HQT0dZR+AlfA@public.gmane.org>]

Don't pass h->xyz_len etc as lengths after freeing h!  Send
the result of sizeof(name->xyz) directly.

Changelog: Jun 23: resend with new description which accurately
	describes what is being fixed (figured out by Nathan Lynch).
