[OpenMP] Fix inconsistent task state if hot team is not used

This patch fixes the inconsistent task state when hot team is not used.
When the primary thread executes `__kmp_join_call`, it calls `__kmp_free_team`,
where worker threads will get destroyed if not using hot team. The destroy of
worker threads also reset their task state. However, the primary thread's is not
reset. When the next parallel region is encountered, in `__kmp_task_team_sync`,
the task state of thread will be flipped. Since the state of primary thread is not
reset, it is still 1, but all the worker threads will be 0, this leads to the
inconsistent task state, causing those threads are using completely different
task team.

Fix #59190.
