Vincent Guittot ba4a2f6d99 sched/fair: Fix imbalance overflow
[ Upstream commit 91dcf1e8068e9a8823e419a7a34ff4341275fb70 ]

When local group is fully busy but its average load is above system load,
computing the imbalance will overflow and local group is not the best
target for pulling this load.

Fixes: 0b0695f2b3 ("sched/fair: Rework load_balance()")
