When there are tensors registered with register buffer in the weight file, the weights are only loaded on device 0 when loading weights across multiple devices.

Research direction
No file, entry point, or test is named. Start by reproducing loading a weight file containing tensors registered with register_buffer across multiple devices, then trace the weight-loading path and its device placement. Done means registered-buffer tensors are distributed across the target devices rather than loaded only on device 0.
