KVM: s390/mm: Fix storage key corruption during swapping
Since 3.12 or more precisely commit 0944fe3f4a32 ("s390/mm:
implement software referenced bits") guest storage keys get
corrupted during paging. This commit added another valid->invalid
translation for page tables - namely ptep_test_and_clear_young.
We have to transfer the storage key into the pgste in that case.
