[LU-12763] Use alternate ping processing for non-mr peers

• Type: Bug

Description

Router peers without multi-rail capabilities (i.e. older Lustre
versions) or router peers that have discovery disabled need to use
the alternate ping processing introduced by LU-12422. Otherwise,
these peers go through the normal discovery processing, but their
remote network interfaces are never added to the peer object. This
causes routes through these peers to be considered down when
avoid_asym_router_failure is enabled.

I set priority on this to Critical because the bug can prevent a filesystem from being useable through non-mr routers.
