Fix reload_model_params failure when loading MoE models with explicit state_dict

[eternally-z]

What does this PR do ?

This PR fixes a bug in _build_model_param_to_state_dict_param_map method. The issue occurs when calling reload_model_params(state_dict) with an explicit state_dict for MoE models.

Since the string "weight1" is a substring of "weight10" and "weight11", the condition name in k evaluates to True for all of them.The number of matched_keys becomes greater than 1, triggering the following assertion:

AssertionError: Parameter decoder.layers.0.mlp.experts.linear_fc1.weight1 has 11 matches in state dict
