Devlink health dump get callback should take devlink lock as any other
devlink callback. Otherwise, since devlink_mutex was removed, this
callback is not protected from a race of the reporter being destroyed
while handling the callback.
Add devlink lock to the callback and to any call for
devlink_health_do_dump(). This should be safe as non of the drivers dump
callback implementation takes devlink lock.
As devlink lock is added to any callback of dump, the reporter dump_lock
is now redundant and can be removed.

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.
