Nirmoy Das 3f66bf401e drm/amdgpu: fix compute queue priority if num_kcq is less than 4
Compute queues are configurable with module param, num_kcq.
amdgpu_gfx_is_high_priority_compute_queue was setting 1st 4 queues to
high priority queue leaving a null drm scheduler in
adev->gpu_sched[hw_ip]["normal_prio"].sched if num_kcq < 5.

This patch tries to fix it by alternating compute queue priority between
normal and high priority.

Fixes: 33abcb1f5a (drm/amdgpu: set compute queue priority at mqd_init)

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.
