[openib-general] [PATCH] Minor fix for ibnetdiscover

[Jason Gunthorpe]

Trivial, ibnetdiscover does not display some switches for some
topologies. This seems to come up if you connect a CA to a switch
but nothing else to the switch.

Output before:
# Topology file: generated on Tue Feb 28 18:21:30 2006
#
# Max of 1 hops discovered
# Initiated from node 0002c9020020d654 port 0002c9020020d655

After:
