Since we are already iterating the ZAP, we have exact string key to remove, we do not need to call zap_remove_int() with the int key we just converted, we can call zap_remove() for the original string.

This should make no functional change, only a micro-optimization.

Types of changes

  • Bug fix (non-breaking change which fixes an issue)
