What problem does this PR solve?
Issue Number:
#2554
Problem Summary:
当一个bthread（taskmeta中的attr.keytable_pool = null）的生命周期结束，且其拥有keytable实例时。在销毁keytable时会调用由用户创建bthread_key_create(bthread_key_t* key, void (destructor)(void data))中传入的destructor析构函数，如果destructor内部使用了bthread-mutex并挂起的话，bthread恢复后所在的task_group会发生变化。在现有的task_runner实现中，如果在return_keytable后不重新指定task_group的话，调用ending_sched(&g)会出现错误。
