    x86emul: remove local variable to address MISRA C:2012 Rule 5.3
    
    The local variable removed by this commit shadowed another declared in
    an outer scope and thus violates Rule 5.3. It was introduced as part of
    a refactoring by commit abf5fb62f73d0dbeabc6a8cd6dbb55174b36c8d1.
    
    No functional changes.
