sched/cache: Fix stale preferred_llc for a new task
On fork without CLONE_VM, the child gets a new mm,
the parent's preferred_llc value is stale for the
child.
Fix this by resetting the task's preferred_llc to -1.
This bug was reported by sashiko.
Fixes: 47d8696b95f7 ("sched/cache: Assign preferred LLC ID to processes")
