I'm not sure why the wrapper doesn't work here.
If I change this to `self.as_mut_ptr()`, then compiler tries to apply
`ObjectDeref::as_mut_ptr` and complains:
the trait `qom::ObjectType` is not implemented for `bindings::MemoryRegion`
But when I modify the function signature to &self like:
diff --git a/rust/qemu-api/src/memory.rs b/rust/qemu-api/src/memory.rs

Then the Wrapper's as_mut_ptr() can work.
