A few minor fixes for patches 1 and 2 of Joao's series adding stats
support to the libxl driver
https://www.redhat.com/archives/libvir-list/2015-November/msg00489.html
I only noticed the minor flaws while reviewing patches later in the series,
after already committing patches 1 and 2.
Jim Fehlig (2):

libxl: don't unlock virDomainObj if refcnt is 0

New subject: [libvirt] [PATCH 1/2] libxl: unref libxlDriverConfig object
Commits b6e19cf4 and 6472e54a missed unref'ing the
libxlDriverConfig object. Add missing calls to virObjectUnref.

Looks great and also tested this series. I see you also moved cfg init further
down which avoids unnecessary initialization for some cases.

And it looks this mistake is also on all patches that use libxlDomainObjEndJob
so will fix that on the next version (interface, block, getalldomainstats.
