Subject: vhost-user: delete net client if necessary
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c67daf4a24442d1bb404a11a6a54dc45ea10f234;p=qemu.git

vhost-user: delete net client if necessary

As qemu_new_net_client create new ncs but error happens later,
ncs will be left in global net_clients list and we can't use them any
more, so we need to cleanup them.
