Subject: [PATCH] KVM: arm64: selftests: Fix multiple versions of GIC creation

Commit 98f94ce42ac6 ("KVM: selftests: Move KVM_CREATE_DEVICE_TEST code to
separate helper") wrongly converted a "real" GIC device creation to
__kvm_test_create_device() and caused the test failure on my D05 (which
supports v2 emulation). Fix it.

Fixes: 98f94ce42ac6 ("KVM: selftests: Move KVM_CREATE_DEVICE_TEST code to separate helper")
