When queuing work to send the NETDEV_BONDING_INFO netdev event, it's
possible that when the work is executed, the pointer to the slave
becomes invalid. This can happen if between queuing the event and the
execution of the work, the net-device was un-ensvaled and re-enslaved.
Fix that by queuing a work with the data of the slave instead of the
slave structure.
Fixes: 69e6113343cf ('net/bonding: Notify state change on slaves')

Move slave state changes to a helper function, this is a pre-step for adding
functionality of dispatching an event when this helper is called.
This commit doesn't add new functionality.
