Update difflogic_kernel.cu

Hi, when i compile difflogic, it failed here.
error: expected an expression
const union scalar_t_ val = {.signed_scalar = b[row * class_size + i][col / bit_count]};
^
this error, i don't understand why compiler can't init 2nd variable of the union scalar_t_, so i switch them and then it worked.

Thanks so much for the issue report & the pull request! With the acceptance of our NeurIPS Oral paper "Convolutional Differentiable Logic Gate Networks", I'm working on a major revision and will also include your bugfix in the revision.
