[Bug]: The status of the Import Task is ImportComplete and should not undergo any further changes

[lentitude2tk]

Is there an existing issue for this?

• I have searched the existing issues

Environment

- Milvus version:2.4
- Deployment mode(standalone or cluster):standalone

Current Behavior

1. If the Import Task has already been marked as Completed.
2. If the collection is dropped, the statuses of importTask and preImportTask will be adjusted to Failed, which can easily cause confusion.
3. Completed is intended to be a terminal state by design and should not be altered under any circumstances.

Expected Behavior

1. If the Import Task has already been marked as Completed.
2. Dropping the collection should not affect the status of this task.

Steps To Reproduce

Follow the current behavioral steps to reproduce.
