pc-dimm: get_memory_region() will not fail after realize
Let's try to reduce error handling a bit. In the plug/unplug case, the
device was realized and therefore we can assume that getting access to
the memory region will not fail.
For get_vmstate_memory_region() this is already handled that way.
Document both cases.
