Takuya UESHIN bcc595c112 [SPARK-36310][PYTHON] Fix IndexOpsMixin.hasnans to use isnull().any() ... ### What changes were proposed in this pull request? Fix `IndexOpsMixin.hasnans` to use `IndexOpsMixin.isnull().any()`. ### Why are the changes needed? `IndexOpsMixin.hasnans` has a potential issue to cause `a window function inside an aggregate function` error. Also it returns a wrong value when the `Series`/`Index` is empty. ```py >>> ps.Series([]).hasnans None ``` whereas: ```py >>> pd.Series([]).hasnans False ``` `IndexOpsMixin.any()` is safe for both cases. ### Does this PR introduce _any_ user-facing change? `IndexOpsMixin.hasnans` will return `False` when empty. ### How was this patch tested? Added some tests. Closes #33547 from ueshin/issues/SPARK-36310/hasnan.
