[PATCH v6 1/6] cat-file: add declaration of variable i inside its for loop

[Eric Ju <eric.peijian@xxxxxxxxx>]

Some code used in this series declares variable i and only uses it
in a for loop, not in any other logic outside the loop.

Change the declaration of i to be inside the for loop for readability.
