scsi: qla2xxx: edif: Reduce Initiator-Initiator thrashing

This patch uses GFFID switch command to scan whether remote device is
Target or Initiator mode.  Based on that info, driver will not pass up
Initiator info to authentication application. This helps reduce unnecessary
stress for authentication application to deal with unused connections.
