Subject: [infiniband] init neigh->dgid.raw on bonding events

O-Subject: [Patch RHEL5.5] [ipoib] init the neigh->dgid.raw struct on bonding
	events
Bugzilla: 538067

We are confusing the bond structures by failing to init the dgid.raw struct
to 0 in order to force re-setting arp and other info on a bonded slave when
it was previously the active link, then it failed, then it came back to
being active.
