Subject: [PATCH v2] KVM: selftests: fix hyperv_clock test

The test was mistakenly using addr_gpa2hva on a gva
and that happened to work accidentally.

commit 106a2e766eae ("KVM: selftests:
Lower the min virtual address for misc page allocations")
revealed this bug.

Fixes: 2c7f76b4c42b ("selftests: kvm: Add basic Hyper-V clocksources tests")
