[Intel-gfx] [PATCH 2/3] drm/i915/dg2: Add initial gt/ctx/engine workarounds

This issue was not catched by CI, because of series of unfortunate events.
Before, CI has rebooted without module blocklist, and CI catched boot-time
dmesg correctly and marked it as 'ci at boot' test with failure if there was a taint.
I've been doing changes to make blocklisting i915 possible and load it as
the first test of IGT: that'd make possible to remove some workarounds
and integrate the result better on our framework.
The test to decide if i915 should be modprobed was slightly off, and
on these runs where i915 failed to load in boot, it was modprobed again,
and modprobe hanged because of existing i915. Results were not collected.
I've added the condition to the conditional modprobe, and the results
from failed boot-time modprobe should be soon available as before,
eg. CI_DRM_10873 later shards with SNB.
Regards,
Tomi
