virtio-net: properly check the vhost status during status set
Commit 32993698 (vhost: disable on tap link down) tries to disable the vhost also when the peer's link is down. But the check was not done properly, the vhost were only started when: 1) peer's link is not down 2) virtio-net has already been started. Since == have a higher precedence than &&, place a brace to make sure both the conditions were met then does the check. This fixes the crash when doing a savem after set the link off which let qemu crash and complains: virtio_net_save: Assertion `!n->vhost_started' failed. Cc: Michael S.
