Fix check of ha enablement of l3 agent

When neutron-server and nova-compute are deployed on the same host (non-HA),
while neutron-l3 is deployed on separate machines in a HA cluster the check as
it was before the fix would falsely assume HA mode for the openvswitch-agent on
the compute nodes. As a result the agent is not started there.
