Invert Index in caller and index in transaction in the serialization benchmark

[LucasSte]

Problem

In #6829, I refactored InstructionAccount and created a constructor for it. As a consequence, we don't have named fields anymore during initialization and we must pass the arguments to the constructor in the correct order.

In my refactor, I did not pay attention to one case where the initialization of the struct members did not follow the same order of the constructor parameters. See https://github.com/anza-xyz/agave/pull/6829/files#diff-4d03f27ca1e78f3acca722a473b99537c734ec252882d32681cb88a29e727365R95-R102.

Summary of Changes

Invert the indexes for the correct usage.
