From: Ivan Ilchenko <ivan.ilchenko@oktetlabs.ru>

Rx queue setup finish function may report wrong number of
allocated mbufs in case of in-order feature. Fix the
function to not ignore allocation error and count only
successfully allocated number of buffers.

Fixes: e5f456a98d3 ("net/virtio: support in-order Rx and Tx")
Cc: stable@dpdk.org
