When rte_pktmbuf_attach_extbuf() is used, the driver should not decrease
the reference count in its callback function hn_rx_buf_free_cb, because
the reference count is already decreased by rte_pktmbuf. Doing it twice
may result in underflow and driver may never send an ack packet over
vmbus to host.
Also declares rxbuf_outstanding as atomic, because this value is shared
among all receive queues.
