This is an update version of last version to fix the handling of polling errors in vhost/vhost_net.
Currently, vhost and vhost_net ignores errors of polling which can lead kernel crashing for buggy/malicious userspace. Fix this by extending the idea of tx polling state to all other vhost_polls and changing the state only when polling succeed.
