While looking at how to best add the follow-up code for detecting kernel lockdown, I noticed a few places where delete in BPF maps is done before we actually stop using the map memory. While the chances of collision in BPF maps are small, it's possible that another thread with a goroutine hashes into the same memory location, before we stop using the memory. This PR moves few deletes into a safe spot.
