Christian Borntraeger b56433cb78 s390/pgtable: Fix check for pgste/storage key handling
pte_present might return true on PAGE_TYPE_NONE, even if
the invalid bit is on. Modify the existing check of the
pgste functions to avoid crashes.

[ Martin Schwidefsky: added ptep_modify_prot_[start|commit] bits ]
