nvme-fc: add support for duplicate_connect option

Browse source

Adds support for the duplicate_connect option. When set to true,
checks whether there's an existing controller via the same host port
and target port for the same host (hostnqn, hostid) to the same
subsystem. Fails the connection request if an existing controller.
