It doesn't. babel (more exactly italian.ldf) is doing it. 

I would say (I haven't checked carefully) that the problem is that
fontspec not only set the font family to latin modern but also define
lmr to be the default fall back family and so latex no longer falls back
to lgrcmr but searches lgrlmr. 

In any case: language files that set encodings are problematic in xetex,
they can break the unicode support. It is best to either avoid them (and
use polyglossia instead) or to at least to load them so early that xetex
aware packages have chance to reset and overwrite as much encoding and
definitions as possible.

In this case it is enough if babel is loaded before fontspec, then
lgrcmr.fd is loaded.
