s390/page: Add memory clobber to page_set_storage_key()
Add memory clobbers to the page_set_storage_key() inline assemblies. This
allows for data dependencies from other code, which is important to prevent
the compiler from reordering instructions if required.
Note that this doesn't fix a bug in existing code; this is just a
prerequisite for upcoming code changes.
