Daniel Wagner 26a57cb355 nvme-fabrics: show well known discovery name 
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

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
