net/virtio-user: fix start with kernel vhost

After reset owner in below patch, we failed to set owner before
sending further vhost messages. It is OK with vhost user implemented
DPDK/VPP/Contrail, but it sees "Operation not permitted" error when
used with vhost kernel.

We fix this by setting owner every time the device is started.
