--------------------------------

commit d2646eed 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.
