Any MLD peer setup call to cdp shall happen only after
clearing the existing MLD peer otherwise the MLD peer's
VDEV reference is lost on recreation. This leads to
VDEV reference leak.
Add history to track the peer setup and destroy sequence,
to understand the CP peer create/destroy sequence when
any such leak happens.
