In current linux.git, gnttab_suspend() and gnttab_resume() are defined and declared unconditionally. However, their only in-tree callers reside in drivers/xen/manage.c, which are guarded by CONFIG_HIBERNATE_CALLBACKS. Match the helper scope to their callers by wrapping the definitions in CONFIG_HIBERNATE_CALLBACKS and providing no-op stubs in the header. This fixes the config-scope mismatch and reduces the code footprint when hibernation callbacks are disabled.
