Felix Lange ed97517ff4 p2p/discover: bump failure counter only if no nodes were provided (#19362)
This resolves a minor issue where neighbors responses containing less
than 16 nodes would bump the failure counter, removing the node. One
situation where this can happen is a private deployment where the total
number of extant nodes is less than 16.
