    x86: Fix incorrect scope of setting `shared_per_thread` [BZ# 30745]
    
    The:
    
    ```
        if (shared_per_thread > 0 && threads > 0)
          shared_per_thread /= threads;
    ```
    
    Code was accidentally moved to inside the else scope.  This doesn't
    match how it was previously (before af992e7abd).
    
    This patch fixes that by putting the division after the `else` block.
    
    (cherry picked from commit 084fb31bc2c5f95ae0b9e6df4d3cf0ff43471ede)
