[PATCH v2 023/144] KVM: selftests: Drop @test param from kvm_create_device()

[Sean Christopherson]

Remove the two calls that pass @test=true to kvm_create_device() and drop
the @test param entirely.  The two removed calls don't check the return
value of kvm_create_device(), so other than verifying KVM doesn't explode,
which is extremely unlikely given that the non-test variant was _just_
called, they are pointless and provide no validation coverage.
