When sending multiple requests, rte_mp_request_sync can succeed sending a few of those requests, but then fail on a later one and in the end return with rc=-1. The upper layers - e.g. device hotplug - currently handles this case as if no messages were sent and no memory for response buffers was allocated, which is not true. Fixed by always freeing the buffers.
