LU-15138 lnet: Fail peer add for existing gw peer

If there's an existing peer entry for a peer that is being added
via CLI, and that existing peer was not created via the CLI, then
DLC will attempt to delete the existing peer before creating a new
one. The exit status of the peer deletion was not being checked.
This results in the ability to add duplicate peers for gateways,
because gateways cannot be deleted via lnetctl unless the routes
for that gateway have been removed first.
