    x86/shadow: sh_rm_write_access_from_sl1p() is HVM-only
    
    The function is used from (HVM-only) OOS code only - replace the
    respective #ifdef inside the function to make this more obvious. (Note
    that SHOPT_OUT_OF_SYNC won't be set when !HVM, so the #ifdef surrounding
    the function is already sufficient.)
