We never checked for errors on add_disk() as this function returned void. Now that this is fixed, use the shiny new error handling. Since we now can tell for sure when a disk was added, move setting the bit NVME_NSHEAD_DISK_LIVE only when we did add the disk successfully. Nothing to do here as the cleanup is done elsewhere. We take care and use test_and_set_bit() because it is protects against two nvme paths simultaneously calling device_add_disk() on the same namespace head.

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.
