[Qemu-devel] [PULL v2 25/28] qdev-props: remove errp from GlobalProperty

["Marc-André Lureau" <marcandre.lureau@redhat.com>]

All qdev_prop_register_global() set &error_fatal for errp, except
'-rtc driftfix=slew', which arguably should also use &error_fatal, as
otherwise failing to apply the property would only report a warning.
