qla2x00t-32gbit: edif: Reduce N2N thrashing at app_start time

Browse Source 
For N2N + remote WWPN is bigger than local adapter, remote adapter will
login to local adapter while authentication application is not running.
When authentication application starts, the current session in FW needs to
to be invalidated.

Make sure the old session is torn down before triggering a relogin.
