After mlx4 driver is converted to do locked reload, devlink_region_snapshot_create() may be called from both locked and unlocked context. Note that in mlx4 region snapshots could be created on any command failure. That can happen in any flow that involves commands to FW, which means most of the driver flows. So resolve this by removing dependency on devlink->lock for region snapshots list consistency and introduce new mutex to ensure it.

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.
