From: Michal Privoznik <mpriv...@redhat.com>
Inside of libxlMakeDomainCapabilities() there are some functions
called and basically all of them never return anything but zero
(indicating success). Yet, they are called in a fashion that
suggests otherwise. Turn those functions into void and drop
checks for their retvals.
