freertos: Fix issue with bootup failure in ESP_MAIN_TASK_AFFINITY_CPU1 config

Browse Source 
Idle tick hook that indicates completion of scheduler init must be launched
on other core than the one where main task runs. Earlier it was assumed that
main task shall always run on PRO cpu but that behavior can be changed with
ESP_MAIN_TASK_AFFINITY_CPU1 and hence this fix.
