This whole function can probably go away now?

The function is still needed to access the private member
gamepad_shared_buffer_, but the parameter is no longer needed. I removed taht
and rename the method.

     base::ProcessHandle process) {
-  base::SharedMemoryHandle renderer_handle;
-  gamepad_shared_buffer_->shared_memory()->ShareToProcess(process,
-                                                          &renderer_handle);
-  return renderer_handle;
+  return gamepad_shared_buffer_->shared_memory()->handle().Duplicate();
 }

   // TODO(heke): Use mojo::SharedBuffer rather than base::SharedMemory in
   // GamepadSharedBuffer. See crbug.com/670655 for details
   base::SharedMemoryHandle handle = base::SharedMemory::DuplicateHandle(
       gamepad_shared_buffer_->shared_memory()->handle());
   return mojo::WrapSharedMemoryHandle(handle, sizeof(GamepadHardwareBuffer),
                                       true /* read_only */);
