[PATCH v1 0/2] s390/mm: fix improper use of __storage_key_init_range

This small series fixes two cases in which the last address in the
range was passed as end address. This was still functionally correct,
since __storage_key_init_range() will still loop over single pages and
correctly clear the given range, but it will be slower than clearing
the storage keys for the whole 1M block with a single instruction.
