[CI] drm/i915/gt: Use kmemdup_array instead of kmemdup for multiple allocation

[Andi Shyti <andi.shyti@linux.intel.com>]

From: Yu Jiaoliang <yujiaoliang@vivo.com>

Let the kememdup_array() take care about multiplication and possible
overflows.

v2:
- Change subject
- Leave one blank line between the commit log and the tag section
- Fix code alignment issue

v3:
- Fix code alignment
- Apply the patch on a clean drm-tip

Hi Yu,

I am resending this patch because this never reached the mailing
list and it didn't get picked up by CI. Maybe it's going through
some manual spam check so that it might take a bit of time.

You should have seen it here[*] as you can see your previous
patches.

Andi
