Commit b7ecba0f6f6 ("docs/devel/loads-stores.rst: Document our
various load and store APIs") mentioned cpu_physical_memory_*()
methods are legacy, the replacement being address_space_*().

Propagate the address space to walk_pte(), then replace the
cpu_physical_memory_read() by address_space_read(). Since the
monitor command are run with a vCPU context, use its default
address space. As with the previous implementation, ignore
whether the memory read succeeded or failed.
