[PATCH 5.13 052/300] sched/numa: Fix is_core_idle()

[Greg Kroah-Hartman]

From: Mika Penttilä <mika.penttila@xxxxxxxxx>

[ Upstream commit 1c6829cfd3d5124b125e6df41158665aea413b35 ]

Use the loop variable instead of the function argument to test the
other SMT siblings for idle.

Fixes: ff7db0bf24db ("sched/numa: Prefer using an idle CPU as a migration target instead of comparing tasks")
