When rapidly rescanning for new namespaces nvme_mpath_add_sysfs_link() may be
called for a block device not added to sysfs. But NVME_NS_SYSFS_ATTR_LINK
had already been set, so when checking this device a second time we will fail
to create the link.
Fix this by exchanging the order of the block device check and the
NVME_NS_SYSFS_ATTR_LINK bit check.

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 reStructuredText 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.
