sched/topology: Fix off by one bug
[ Upstream commit 993f0b0510dad98b4e6e39506834dab0d13fd539 ]
With the addition of the NUMA identity level, we increased @level by
one and will run off the end of the array in the distance sort loop.
Fixed: 051f3ca02e46 ("sched/topology: Introduce NUMA identity node sched domain")
