commit d2646eed7b19a206912f49101178cbbaa507256c upstream.
While a session is in the middle of a relogin, a late RSCN can be delivered from switch. RSCN trigger fabric scan where the scan logic can trigger another session login while a login is in progress. Reduce the extra trigger to prevent multiple logins to the same session.
