Leaving TlsChildHandle with the stale handle causes later use of https
with the http instance to incorrectly skip tls reconfiguration, use
the stale handle, and eventually call a garbage function pointer.

thanks a lot for tracking this down!

I've reopened BZ#1917, and linked your patch email in a new comment.

But, I'd also like to assign the BZ to you, if that's OK with you. Can
you please register in the TianoCore bugzilla instance for that?

Certainly, account created and assignment taken. Thanks Laszlo.
