VF unload gets stuck in MANA driver, when the host is not responding. The function mana_dealloc_queues() tries to clear the inflight packets, and gets stuck in while loop. Another problem in this scenario is the timeout from hwc send request. These patch add fix for the same. In mana driver we are adding a timeout in the while loop, to fix it. Also we are adding a new attribute in mana_context, which gets set when mana_hwc_send_request() hits a timeout because of host unresponsiveness.
