addDLL_PEi386 loads all DLLs twice

In addDLL_PEi386 we currently have:

    for (cFlag = flags_start; cFlag < 2; cFlag++)
    {
        for (cFormat = 0; cFormat < 4; cFormat++)
        {
            snwprintf(buf, bufsize, formats[cFormat], dll_name);
            instance = LoadLibraryExW(buf, NULL, flags[cFlag]);
            if (instance == NULL) {
                if (GetLastError() != ERROR_MOD_NOT_FOUND)
                {
                    goto error;
                }
            }
            else
            {
                break; /* We're done. DLL has been loaded.  */
            }
        }
    }

This is subtly wrong. In particular, on success we break, which only breaks out of the first for. Consequently we will potentially load the DLL again with a different set of flags. I believe this is harmless but certainly not ideal.
