[dpdk-dev] [PATCH] net/virtio: fix memory leak in dev close

[Gaoxiang Liu]

Free the "intr_handle" memory in virtio_user_dev_uninit() to
avoid memory leak.
when virtio user dev closes, the "intr_handle" memory is not freeed
that is alloced in virtio_user_fill_intr_handle().

Fixes: 7f468b2ebfad ("net/virtio: release port upon close")
