If one host crashes and soft reboots, the other host may not see a link down event. Then when the crashed host comes back up, the surviving host may not know the link was reset and the NTB clients may not work without being reset. To solve this, we send a LINK_FORCE_DOWN message to each peer every time we come up, before we register the NTB device. If a surviving host still thinks the link is up it will take it down immediately. In this way, once the crashed host comes up fully, it will send a regular link up event as per usual and the link will be properly restarted. While we are in the area, this also fixes the MSG_LINK_UP message that was in the link down function that was reported by Doug Meyers.
