sched_ext: Add scx_enabled() test to @start_class promotion in put_prev_task_balance()

Browse source

SCX needs its balance() invoked even when waking up from a lower priority
sched class (idle) and put_prev_task_balance() thus has the logic to promote
@start_class if it's lower than ext_sched_class. This is only needed when
SCX is enabled. Add scx_enabled() test to avoid unnecessary overhead when
SCX is disabled.
