[Bug] Logs report "failed to acquire semaphore" during deletion about eksctl

[cPu1]

@artem-nefedov, this is a bug in the logging and concurrency handling but it should not affect normal operation of the command. That part of the codebase is a bit dated and could use some refactoring. We'll look into this soon.

We also encountered the same error log information when deleting EKS version 1.30, and our eksctl version is 0.183.
the error message that is following:
