BZ #2909, https://bugzilla.tianocore.org/show_bug.cgi?id=2909 When Http->Configure() is invoked with HttpConfigData set to NULL to reset the EFI HTTP instance, TLS child instance is destroyed but HttpInstance->TlsChildHandle is not set to NULL. After reconfiguring HTTP through Http->Configure() and sending the HTTP request to HTTPS URL, TLS child instance is not recreated because HttpInstance->TlsChildHandle is not NULL.
