Currently, polling error were ignored in vhost. This may lead some issues (e.g
kenrel crash when passing a tap fd to vhost before calling TUNSETIFF). Fix this
by:
Can this kernel crash be reproduced by hand?

Yes, it could be simply reproduced by: open a tap fd but does not cal
TUNSETIFF, then pass it to qemu and enable vhost.
