Jakub Kicinski 3534c7b7b3 devlink: make health report on unregistered instance warn just once 
[ Upstream commit 6f4b98147b ]

Devlink health is involved in error recovery. Machines in bad
state tend to be fairly unreliable, and occasionally get stuck
in error loops. Even with a reasonable grace period devlink health
may get a thousand reports in an hour.

In case of reporting on an unregistered devlink instance
the subsequent reports don't add much value. Switch to
WARN_ON_ONCE() to avoid flooding dmesg and fleet monitoring
dashboards.

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.
