Subject: [net-next v0 12/15] net/mlx5: E-switch, Reuse mlx5_eswitch_set_vport_mac

From: Parav Pandit <parav@...dia.com>

mlx5_eswitch_set_vport_mac() routine already does necessary checks which
are duplicated in implementation of
mlx5_devlink_port_function_hw_addr_set().

Hence, reuse mlx5_eswitch_set_vport_mac() and cut down the code.
