RDMA/mana_ib: Handle net event for pointing to the current netdev

Browse source

commit bee35b7161 upstream.

When running under Hyper-V, the master device to the RDMA device is always
bonded to this RDMA device. This is not user-configurable.

The master device can be unbind/bind from the kernel. During those events,
the RDMA device should set to the current netdev to reflect the change of
master device from those events.
