s390x: introduce s390_get_memory_limit()
Let's add s390_get_memory_limit(), to query what has been successfully set via s390_set_memory_limit(). Allow setting the limit only once. We'll remember the limit in the machine state. Move s390_set_memory_limit() to machine code, merging it into set_memory_limit(), because this really is a machine property.
