Commit 60b176c3d0f0d5037acfa5e27c7753f657833a0b introduced a bug that
when editing an XML with cputune similar to this:
Thanks for fixing this.
...
<vcpu placement='static' current='1'>2</vcpu>
<cputune>
<vcpupin vcpu="1" cpuset="0"/>
</cputune>
...
results in formatted XML that looks like this:
...
<vcpu placement='static' current='1'>2</vcpu>
<cputune>
</cputune>
...
That is caused by a condition depending on def->cputune.vcpupin being
set rather than checking def->cputune.nvcpupin. Notice that nvcpupin
can be 0 and vcpupin can still be allocated since it's a pointer to an
array, so no harm done there.

This is a good fix, but I don't think it fixes the problem what commit
message describes. As both def->cputune.vcpupin and
def->cputune.nvcpupin should be true here for the testing case you
wrote in the commit message.
And as long as we try to use nvcpupin here, we should use nvcpupin
when formating "</cputune>" too.
