[libvirt] [libvirt PATCH v6 13/15] xen_common: Change xenParsePCIList to using virConfGetValueStringList

[Fabiano Fidêncio]

The `if (!list || list->type != VIR_CONF_LIST)` couldn't be written in a
100% similar way as `if (virConfGetValueStringList(conf, "pci", false,
&pcis) <= 0)` leads us to just ignore any error and return 0 in case of
failure. However, for what's needed in this function, this is the
closest to the original that we can get and it shouldn't change the
function behaviour.
