[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.
