From: Roman Bolshakov <r.bolshakov@yadro.com> [ Upstream commit 5e6b01d84b9d20bcd77fc7c4733a2a4149bf220a ] qlt_handle_login schedules session for deletion even if a login is in progress. That causes login bouncing, i.e. a few logins are made before it settles down. Complete the first login by sending Notify Acknowledge IOCB via qlt_plogi_ack_unref if the session is pending login completion.
