scsi: qla2xxx: Add error handling for PLOGI ELS passthrough

Add error handling logic to ELS Passthrough relating to NVME devices.
Current code does not parse error code to take proper recovery action,
instead it re-logins with the same login parameters that encountered the
error. Ex: nport handle collision.
