[PATCH] net: use peer when purging queue in qemu_flush_or_purge_queue_packets()

[Jason Wang <jasowang@redhat.com>]

The sender of packet will be checked in the qemu_net_queue_purge() but
we use NetClientState not its peer when trying to purge the incoming
queue in qemu_flush_or_purge_packets(). This will trigger the assert
in virtio_net_reset since we can't pass the sender check.

Fix by using the peer.
