wifi: iwlwifi: clear link_id in time_event

Before sending a SESSION PROTECTION cmd the driver checks if
the link_id indicated in the time event (and for which the cmd will be
sent) is valid and exists.
Clear the te_data::link_id when FW notifies that a session protection
ended, so the check will actually fail when it should.
