[libvirt] PATCH: Fix deadlock upon config file reload

[Daniel P. Berrange]

Turned out there was a small locking bug when reloading domain config
files after SIGHUP. I committed the following patch to add in the missing
unlock call. This was one of the files I'm unable to do static analysis
on, hence why it was missed.
