We should fix the test code to pass the im2col/col2im path even in cuDNN-enabled environments. |

I fixed tests to check im2col version even if cuDNN is enabled. |

As for @beam2d's fix, it looks good for me. |

OK, then I'll merge. |

When CuDNN is not used,
Convolution2D.backward_gpuusescuda.linalg, which is no longer available after CuPy is introduced. This PR removes dependency oncuda.linalg.dotandcuda.linalg.add_dotand usescuda.cupy.dotinstead.
