[SCSI] fcoe: add check to fail gracefully in bonding mode
This patch adds a check to fail gracefully when the netdevice
is bonded. Previously, the error was detected but the stack
would continue to load. This resulted in a partially enabled
fcoe intance and errors when the fcoe instance was destroy.
