Subject: net/virtio: fix interrupt handle leak
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7b9195154926b808e3ae23750eaff3e81cd5f529;p=dpdk.git

net/virtio: fix interrupt handle leak

Free memory of interrupt handle in virtio_user_dev_uninit() to
avoid memory leak.
when virtio user dev closes, memory of interrupt handle is not freed
that is allocated in virtio_user_fill_intr_handle().

Fixes: 3d4fb6fd2505 ("net/virtio-user: support Rx interrupt")
