Fix resource leak : 23614

This problem is caused by managing a number of operations to be processed asynchronously in the initialization list.
If the initialization of a function that needs to be processed asynchronously fails, we did not free the previously added asynchronous functions.
To solve this problem, we modified the asynchronous initialization function list to be deleted from the memory when the function creation to be processed asynchronously fails and when the plugin is unloaded.
