Fix a racing issue when jobs on 2 rings timeout simultaneously. If 2 rings timed out at the same time, the amdgpu_device_gpu_recover will be reentered. Then the adev->gmc.xgmi.head will be grabbed by 2 local linked list, which may cause wild pointer issue in iterating. lock the device earily to prevent the node be added to 2 different lists. also increase karma for the skipped job since the job is also timed out and should be guilty.

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.
