Subject: [PATCH] KVM: PPC: Book3S HV: Add H_VIRT mapping for tracing exits

The macro kvm_trace_symbol_exit is used for providing the mappings
for the trap vectors and their names. Add mapping for H_VIRT so that
trap reason is displayed as string instead of a vector number when using
the kvm_guest_exit tracepoint.
