PR #14219 added indexer_k_dtype to the dict returned by update_sparse_attention_indexer_config(), but the DSv4 code path also passes it as an explicit keyword argument. This causes TypeError: got multiple values for keyword argument 'indexer_k_dtype' when loading DeepSeek-V4 models.

Remove the redundant explicit argument since it is already included in the indexer_config dict via **indexer_config.
