[libvirt] [PATCH 5/6] xenconfig: Resolve Coverity RESOURCE_LEAK

[John Ferlan]

Commit id '2c78051a' added xenFormatXLDomainDisks which used the
virConfSetValue to set the 'diskVal' and handle/own the memory for
diskVal. However, if diskVal->list == NULL, the memory for diskVal
wouldn't be VIR_FREE()'d like other similar uses - so added the
VIR_FREE() to resolve the memory leak.

I also noted that the cleanup path should have returned -1 (like other
uses), so I modified that as well while I was making the change.
