Subject: [PATCH] [CK]fix: remove redundant structured sparsity check in
 run_gemm_example.inc (#5612)

## Motivation

This issue if found via
https://github.com/ROCm/rocm-libraries/pull/4302#discussion_r2958603418
and is introduced via https://github.com/ROCm/rocm-libraries/pull/5323.

## Technical Details

The outer `if` and inner `if constexpr` both checked
GemmConfig::UseStructuredSparsity. Merged into a single `if constexpr`
since both preshuffle and UseStructuredSparsity are compile-time
constants.

## Test Plan

<!-- Explain any relevant testing done to verify this PR. -->

## Test Result

<!-- Briefly summarize test outcomes. -->
