In configurations with CONFIG_XEN_BALLOON_MEMORY_HOTPLUG=n
and CONFIG_XEN_BALLOON_MEMORY_HOTPLUG=y, gcc warns about an
unused variable:
drivers/xen/balloon.c:83:12: error: 'xen_hotplug_unpopulated' defined but not
used [-Werror=unused-variable]
Since this is always zero when CONFIG_XEN_BALLOON_MEMORY_HOTPLUG
is disabled, turn it into a preprocessor constant in that case.
