[libvirt] [PATCH] lib: fix no zero arg check for iothread_id

[Luyao Huang]

https://bugzilla.redhat.com/show_bug.cgi?id=1251886

We do not allow delete an iothread which id is 0 in
virDomainDelIOThread, but allow it in virDomainAddIOThread,
Also we will output an error when parse an iothread which id
is 0.

Add a check for iothread_id in virDomainAddIOThread to fix
it.

Is that okay to fix it in this place ?
