[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.
