LU-10391 lnet: missing some peer functionality

For peers if we encounter a bad setup in the peer nis
settings for creation we need to cleanup the entire
peer setup.

For the peers API if one of the peer nis is the same as
the primary nid then treat it as tearing down all peer nis
in the peer deletion case.
