Daniel Wagner daf8c1062d nvme-fabrics: show well known discovery name

[ Upstream commit 26a57cb35548ae67c14871cccbf50da3edb01ea4 ]

The kernel always logs the unique subsystem name for a discovery
controller, even in the case user space asked for the well known.

This has lead to confusion as the logs of nvme-cli and the kernel
logs didn't match.

First, nvme-cli connects to the well known discovery controller to
figure out if it supports TP8013. If so then nvme-cli disconnects and
connects to the unique discovery controller. Currently, the kernel show
that user space connected twice to the unique one.

To avoid further confusion, show the well known discovery controller if
user space asked for it:

  $ nvme connect-all -v -t tcp -a 192.168.0.1
  nvme0: nqn.2014-08.org.nvmexpress.discovery connected
  nvme0: nqn.2014-08.org.nvmexpress.discovery disconnected
  nvme0: nqn.discovery connected

  kernel log:
  nvme nvme0: new ctrl: NQN "nqn.2014-08.org.nvmexpress.discovery", addr 192.168.0.1:8009
  nvme nvme0: Removing ctrl: NQN "nqn.2014-08.org.nvmexpress.discovery"
  nvme nvme0: new ctrl: NQN "nqn.discovery", addr 192.168.0.1:8009
