sched_ext: Route task slice writes through set_task_slice()

Browse source

A later change makes set_task_slice() also drop a pending out-of-band slice
request, so the BPF-triggered writes to p->scx.slice need to funnel through
one place. Introduce set_task_slice() and route those writes through it.
update_curr_scx() decrements curr->scx.slice directly for accounting and is
left alone. No functional change - the helper only assigns p->scx.slice.

v2: Reword the set_task_slice comment to "BPF-triggered writes". (Andrea)
