Subject: scsi: qla2xxx: edif: Fix n2n discovery issue with secure target

Patch-mainline: v5.20-rc1

Git-commit: 789d54a4178634850e441f60c0326124138e7269

References: bsc#1201958

User failed to see disk via n2n topology. Driver used up all login retries

before authentication application started. When authentication application

started, driver did not have enough login retries to connect securely. On

app_start, driver will reset the login retry attempt count.
