Description
In `os::numa_get_leaf_groups` of `os_windows.cpp`, `get_node_list_entry` is called with proper bound check, so it's redundant to check for out-of-index again inside the callee.

Other callers of `get_node_list_entry` also provide the same guarantee.
Comments
Runtime Triage: moving this issue since blocking issue JDK-8244065 is assigned to GC.

Should probably be done after JDK-8244065 so that the patch can be properly tested.
