s390/mm: Use lock_mm_and_find_vma() in do_secure_storage_access()
do_secure_storage_access() uses find_vma() without verifying that the
faulting address is within the returned vma. Add this missing check by
converting to lock_mm_and_find_vma().
This is not a critical fix, since the worst that could happen is a
WARN_ON_ONCE() in folio_walk_start().
