bonding: fix crash when no slave device

Browse Source 
If a bonded device is created when there are no slave devices
there is a loop in bond_ethdev_promiscuous_enable() which results
in a segmentation fault.

The solution is to initialise the current_primary_port to an
invalid port value when the bonded port is created.

Fixes: 2efb58cbab ("bond: new link bonding library")
