[PATCH v2 05/17] hw/s390x/sclp: Use address_space_memory_is_io() in sclp_service_call()

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

When cpu_address_space_init() isn't called during vCPU creation,
its single address space is the global &address_space_memory.

As s390x boards don't call cpu_address_space_init(),
cpu_get_address_space(CPU(cpu), 0) returns &address_space_memory.

We can then replace cpu_physical_memory_is_io() by the semantically
equivalent address_space_memory_is_io() call.
