Oh, thanks for noticing that the code was ignoring return values. I've
just blindly looked at the memory leaks and fixed them without wondering

ACK to the series except the 5/6 patch for xen_xl parser as there is a
new series waiting for review which will revert the code and introduce
a new approach to parse the xen xl configuration.
