[SCSI] fcoe: move packet handlers from fcoe_port to fcoe_interface
The packet handlers need to be tracked in fcoe_interface so there is only one set per net_device. When NPIV is enabled there will be multiple SCSI hosts and multiple fcoe_port structures on a single net_device. The packet handlers match by ethertype and netdev. If the same handler gets registered on a single netdev multiple times, the receive function will be called multiple times for each frame.
