target/s390x: Replace legacy cpu_physical_memory_[un]map() calls (1/3)

Browse Source 
Commit b7ecba0f6f ("docs/devel/loads-stores.rst: Document our
various load and store APIs") mentioned cpu_physical_memory_*()
methods are legacy, the replacement being address_space_*().

Replace the *_map() / *_unmap() methods in mchk_store_vregs().
No behavioral change expected.
