Changed variable name from "h" to "hidden_states" (huggingface#285)

* Changed variable name from "h" to "hidden_states"

Per issue huggingface#198 , changed variable name from "h" to "hidden_states" in the forward function only. I am happy to change any other variable names, please advise recommended new names.

* Update src/diffusers/models/resnet.py
