[PATCH v3 1/5] NetworkPkg/HttpDxe: Decofigure Tcp4 before reconfiguring

["Oliver Steffen" <osteffen@redhat.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2720

Check if the state of the HTTP instance is HTTP_STATE_TCP_CONNECTED, or
HTTP_STATE_TCP_CLOSED and de-configure the Tcp4 instance before
configuring it again.
