[SCSI] libfcoe: fix VN2VN N_Port_ID Beacon source MAC
FC-BB-6 v1.04 7.9.8.14 N_Port_ID Beacon: "A N_Port_ID Beacon is multicast and uses the VN_Port MAC address as source address." Currently, libfcoe is using ENode MAC, this seems ok and functionality wise not a problem in my back to back testing setup, however, just fix this to make libfcoe VN2VN support more spec compliant.
