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.
