conf: Error out if iothread id is missing in iothreadpin

Browse Source 
Defining a domain with the following config:

<domain ...>
  ...
  <iothreads>1</iothreads>
  <cputune>
    <iothreadpin cpuset='1'/>

will result in the following config formatted back:
<domain type='kvm'>
  ...
  <iothreads>1</iothreads>
  <cputune>
    <iothreadpin iothread='0' cpuset='1'/>

After restart the VM would vanish. Since our schema requires the
@iothread field to be present in <iothreadpin> make it required by the
code too.
