Assert was tripped after the lnetctl net del command was executed on sles15build01.

I think the bug is probably in the initial router discovery. When we create the lpni for the primary nid, 192.168.2.20@tcp1, and attach it to peer it is at the end of the list, but I think primary nid is expected to be the first one.
