sched/event: Fix uninitialized need_switch flag issue in event_post()

Browse Source 
The `need_switch` flag was not initialized in `event_post()`. Since it is
    a local variable, it could contain a random non-zero value, leading to
    incorrect behavior.
    In addition, this patch also fixes an issue where the event clearing
    operation in `event_post()` was not performed correctly.
