Subject: nvme-fc: update tagset nr_hw_queues after queues reinit
Patch-mainline: v4.13-rc1
Git-commit: cda5fd1ac5c2c42d1b2e1847aa0438b229c5c068
References: FATE#323952, FATE#322506

We might have more/less queues once we reconnect/reset. For
example due to cpu going online/offline or controller constraints.
