NIFI-14742 Replaced for loop missed by PMD's ForLoopCanBeForeach rule with for each loop.

[dan-s1]

Summary

NIFI-14742
I only found this one instance which was not caught by the PMD's ForLoopCanBeForeach rule.
I tried looking for other cases with Intellij's find in files with the following regular expression
for \(int\s?.+\s?=\s?0
but I did not find any other for loops which could be changed to a for each loop.
