[SCSI] Revert "[SCSI] fcoe: Fix using VLAN ID in creating lport's WWWN/WWPN"
This reverts commit cc0136c2e9c10e889cb36e39710c0eb10707b396.
That commit introduced vlan id info to WWPN but WWPN needs to
remain static as an unique port identifier in the fabric, therefore
variable fabric vlan id info doesn't need to be coded inside WWPN.
After this revert, port arg to fcoe_wwn_from_mac is always zero
but still leaving it as-is okay to later allow users to use NAA 2
scheme with this additional port arg.
Note with this patch, existing zoning using WWPN would require
re-zoning this time only and later no more re-zoning due to any
vlan id changes.
