sched/core: Remove double update_max_interval() call on CPU startup
update_max_interval() is called in both CPUHP_AP_SCHED_STARTING's startup and teardown callbacks, but it turns out it's also called at the end of the startup callback of CPUHP_AP_ACTIVE (which is further down the startup sequence). There's no point in repeating this interval update in the startup sequence since the CPU will remain online until it goes down the teardown path. Remove the redundant call in sched_cpu_activate() (CPUHP_AP_ACTIVE).
