[dpdk-stable] [PATCH v6] net/virtio-user: fix failures when setting filters

[Marvin Liu <yong.liu@intel.com>]

As doc mentioned, Rx/Mac/vlan filters are all supported by best effort.
These control commands should return success.

Fixes: f9b9d1a55775 ("net/virtio-user: add multiple queues in device emulation")
