sched: Pass correct scheduling policy to __setscheduler_class
Commit 98442f0ccd82 ("sched: Fix delayed_dequeue vs
switched_from_fair()") overlooked that __setscheduler_prio(), now
__setscheduler_class() relies on p->policy for task_should_scx(), and
moved the call before __setscheduler_params() updates it, causing it
to be using the old p->policy value.
Resolve this by changing task_should_scx() to take the policy itself
instead of a task pointer, such that __sched_setscheduler() can pass
in the updated policy.
Fixes: 98442f0ccd82 ("sched: Fix delayed_dequeue vs switched_from_fair()")
