pc-dimm: remove unnecessary get_vmstate_memory_region() method
The get_vmstate_memory_region() method from PCDIMMDeviceClass is only
ever called from this class and is never overridden, so it can be converted
into an ordinary function.
This saves us from having to do an indirect call in order to reach it.
