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

[ Upstream commit 789d54a4178634850e441f60c0326124138e7269 ]

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.
