[dpdk-dev] [PATCH 2/2] ipc: fix timeout not properly handled in async

In original implementation, timeout event for an async request
will be ignored. As a result, an async request will never
trigger the action if it cannot receive any reply any more.
We fix this by counting timeout as a processed reply.
