ofproto/bond: Validate active-slave mac.

Browse Source 
That the mac of active-slave is invalid(e.g. 00:00:00:00:00:00)
is incidental. The reason is described as below.

In the bridge_reconfig():
1. bond devices created in port_configure().
2. the bonded interfaces may be disabled even calling bridge_run__(),
   because the interface link is not ready.

The OvS will run bridge_run__() in next loop. In next loop, the
active-slave may be selected. But OvS the bridge_reconfig() again,
the bond_reconfigure() set active-slave mac zero and flag false.
If using the 'ovs-appctl bond/show bond-name' to check active-slave
mac, you will find the mac is zero and mac in the ovsdb is also zero.

The active_slave_mac and active_slave_changed should be initialized
when created.
