s390/mm: add __rcu annotations
Add __rcu annotations so sparse correctly warns only if "slot" gets
derefenced without using rcu_dereference(). Right now we get warnings
because of the missing annotation:
arch/s390/mm/gmap.c:135:17: warning: incorrect type in assignment (different address spaces)
arch/s390/mm/gmap.c:135:17: expected void **slot
arch/s390/mm/gmap.c:135:17: got void [noderef] <asn:4>**
