Ping...
It makes sense as when we use 'memory_region_read_accessor' we check
mr->ops->read.
but when we use 'memory_region_read_with_attrs_accessor', we doesn't check
this.
Thanks,

Alternative approach -- assert that
This can avoid the NULL-deref if the rm doesn't has a
read/write nor write/read_with_attrs callback.
