message: Fix build failure in `bazel test -s --config=opt --cache_test_results=no //tensorflow/python/kernel_tests:init_ops_test`
  With the most recent master the following test fails:
  ```
  bazel test -s --config=opt --cache_test_results=no //tensorflow/python/kernel_tests:init_ops_test
  ...
  ...
  ...
  eye = linalg_ops.eye(n, dtype=self.dtype)
  NameError: global name 'linalg_ops' is not defined
  ```
  This fix fixes the test failure.
