[PATCH] NetworkPkg/HttpDxe: TlsChildHandle is not cleared when reset

["Abner Chang" <abner.chang@hpe.com>]

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.
