[PATCH 10/12] KVM: selftests: Assert that eventfd() succeeds in Xen shinfo test

[Sean Christopherson]

Assert that eventfd() succeeds in the Xen shinfo test instead of skipping
the associated testcase.  While eventfd() is outside the scope of KVM, KVM
unconditionally selects EVENTFD, i.e. the syscall should always succeed.
