'arg': required argument is not specified in attribute idl_module

A required argument was not passed to the idl_module attribute.

The following sample generates C3347:

// C3347.cpp
// compile with: /c
[module(name="xx")];

[idl_module(dllname="x")];    // C3347
// try the following line instead
// [idl_module(name="test", dllname="x")];
