IPoIB: Handle bonding failover race for connected neighbours too
Move up the code that checks for a situation where the remote GID
stored in the ipoib_neigh is different than the one present in the
neighbour (handle gratuitous ARP) or that a bonding fail over has
happened but the neighbour still has a pointer to an ipoib_neigh
created by a different device than the current slave. This will cause
the driver to apply the check also for connected mode neighbours.
