[PATCH 6.12 1102/1102] sched/eevdf: Fix augmented max_slice

6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Vincent Guittot <vincent.guittot@linaro.org>

commit 9a8bc9bb4c3fb3218b4f151f98a722fbeb5b5c34 upstream.

Similarly to se->min_slice, init se->max_slice with se->slice before
enqueueing the entity so the augmented callback computes it correctly
at parent level.

Fixes: 6e3c0a4e1ad1 ("sched/fair: Fix lag clamp")
