KokkosKernels: Gauss-Seidel test fails with CUDA

The Gauss-Seidel test that I reenabled as part of #977 (closed) fails in a CUDA debug build for me, with CUDA 7.5 and GCC 4.8.4. It passes in a non-CUDA Clang 3.9 build with Kokkos::Serial. The error messages look like this:
result_norm_res:3.05254e+36 initial_norm_res:160.873
3: .../Trilinos/packages/tpetra/kernels/unit_test/graph/KokkosKernels_Test_GaussSeidel.cpp:219: Failure
3: Value of: (result_norm_res < initial_norm_res)
3: Actual: false
3: Expected: true
