Fix cycle GAN model random failed on GPU

The calculation of GPU kernel in BN is non-deterministic, failure rate is 1/100 in Dev but seems incremental in CE platform. If on GPU, we disable BN temporarily.

Because we disable BN on GPU, but here we enhance the check on CPU by np.array_equal which means the dy_out and st_out shall be exactly same.
