Image scaling for Inception model in PyTorch incorrect

[rwightman]

For 299 size image you still resize the image to 256 before cropping to 299. You should resize to img_size / 0.875 before cropping. Some of the inception models can get a little better pushing closer to 0.9 for the ratio.

In the past I've benchmarked Inception v3 weights in PyTorch at prec@1 77.436 prec@5 93.476
