In case you will specify graphics like this:
<graphics type='spice' port='-1'/>
or
<graphics type='spice' port='-1' tlsPort='6000'/>
libvirt will automatically add autoport='no'. This leads to an issue
that in qemuProcessStop() we don't release that port because we are
releasing both port if autoport=yes or only port marked as reserved.
If autoport=no but we request to generate port via '-1' we need to mark
that port as reserved in order to release it.
