qemu: Resolve Coverity FORWARD_NULL

If the virJSONValueNewObject() fails, then rather than going to error
and getting a Coverity false positive since it doesn't seem to understand
the relationship between nkeywords, keywords, and values and seems to
believe calling qemuFreeKeywords will cause a NULL deref - just return NULL
