[SCSI] libfcoe: Incorrect CVL handling for NPIV ports

Host doesnt handle CVL to NPIV instantiated ports correctly.
- As per FC-BB-5 Rev 2 CVLs with no VN_Port descriptors shall be treated as
  implicit logout of ALL vn_ports.
- CVL for NPIV ports should be handled before physical port even if descriptor
  for physical port appears before NPIV ports
