David Hildenbrand 7ea0d2d79d drivers/base/memory: add memory block to memory group after registration succeeded
If register_memory() fails, we freed the memory block but already added
the memory block to the group list, not good.  Let's defer adding the
block to the memory group to after registering the memory block device.

We do handle it properly during unregister_memory(), but that's not
called when the registration fails.
