move a little 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
not by the current slave. This
will cause the driver to apply the check also for connected mode neighbours.
This patch was tested against upstream kernel and ofed_kernel.
