xen: don't use page->lru for ZONE_DEVICE memory
Commit 9e2369c06c8a18 ("xen: add helpers to allocate unpopulated
memory") introduced usage of ZONE_DEVICE memory for foreign memory
mappings.
Unfortunately this collides with using page->lru for Xen backend
private page caches.
Fix that by using page->zone_device_data instead.
