This is not true when KFD device\ninitialization fails after probe.\n\nFor example, kgd2kfd_device_init() sets num_nodes before checking\nPCIe atomics support. On Polaris systems without the required atomics,\nit returns before allocating nodes[0], but the kfd_dev remains attached\nto the amdgpu device. A later GPU reset then dereferences nodes[0]->id.\n\nRequire the authoritative KFD initialization flag before walking the\nnode array, matching the existing KFD reset and teardown paths.\n\n(cherry picked from commit 4ac1835823c47903fbb278bbf474773c46f59edc)"
