[PATCH v4 08/17] KVM: selftests: Always assert that vmclear() succeeds

[Sean Christopherson <seanjc@google.com>]

Continue removing dead error "handling", and assert that VMCLEAR
succeeds instead of forcing callers of load_vmcs() to assert success.

For all intents and purposes, no functional change intended.
