Remove device parameter from create_extended_attention_mask_for_decoder
Author: pbelevich
Pull request: yes

# What does this PR do?

This RP removes redundant `device` parameter from `create_extended_attention_mask_for_decoder` that may cause potential issues if passed `device` is not equal `attention_mask.device`, see line [`modeling_utils.py#L610`](https://github.com/huggingface/transformers/blob/6d90d76f5db344e333ec184cc6f414abe2aa6559/src/transformers/modeling_utils.py#L610). Explanation: tracing logic from line 610 to method signature: 
`causal_mask.device` == `attention_mask.device` => `seq_ids.device` == `attention_mask.device` => `device` == `attention_mask.device`

Comments:
_The documentation is not available anymore as the PR was closed or merged._

This seems legit for me, pinging @LysandreJik, @sgugger and @ydshieh to comment on this.


LGTM, as it uses the device from the argument `attention_mask`.
