s390/mm: Fix storage key clearing for guest huge pages
The function __storage_key_init_range() expects the end address to be
the first byte outside the range to be initialized. I.e. end - start
should be the size of the area to be initialized.
The current code works because __storage_key_init_range() will still loop
over every page in the range, but it is slower than using sske_frame().
