qemu: Clean up qemuDomainSetNumaParameters
qemu: Clean up qemuDomainSetNumaParameters

Add whitespace to separate logical code blocks, reformat error messages
and clean up code flow.

This patch changes error handling in some cases where the the loop would
be continued to jump to cleanup instead and error out rather than modify
the domain any further.
