If it were as easy to detect and XFS mount as to check idn2's version
(one function call), and as difficult to access a working idn2
interface, I'd say sure, xfail it.

But in this case, we have a way of testing our interface independently
of kernel bugs - mounting tmpfs gives us a way to *validly* test our
code on a *known good* kernel module.  I don't think we should throw
away that test.

We're allowed to have two tests...
