Subject: [PATCH V6 mlx5-next 07/16] bonding: Add function to get the xmit slave in active-backup mode

Add helper function to get the xmit slave in active-backup mode.
It's only one line function that return the curr_active_slave,
but it will used both in the xmit flow and by the new .ndo to get
the xmit slave.
