Bug: wrong argument name is causing AttributeError

[jaewoosong]

  File "/home/workspace/ao/torchao/_models/llama/eval.py", line 348, in <module>
    args.sparstiy,
    ^^^^^^^^^^^^^
AttributeError: 'Namespace' object has no attribute 'sparstiy'. Did you mean: 'sparsity'?

The file ao/torchao/_models/llama/eval.py has a typo at line 348 which causes AttributeError.
