[libvirt] [PATCH 6/8] Fix printing of pathnames on error in qemuDomainSnapshotLoad.

[Chris Lalancette <clalance@xxxxxxxxxx>]

While doing some testing of the snapshot code I noticed that
if qemuDomainSnapshotLoad failed, it would print a NULL as
part of the error.  That's not desirable, so leave the
full_path variable around until after we are done printing
errors.
