feat(diffusers): don't set seed in params and respect device (#1010)

Browse Source 
**Description**

Follow up of #998 - respect the device used to load the model and do not
specify a seed in the parameters, but rather just configure the
generator as described in
https://huggingface.co/docs/diffusers/using-diffusers/reusing_seeds
