Subject: drm/i915: Skip capturing errors from internal contexts
Git-commit: 03d0ed8a8e93005417c2aa8ea735b247e7a9d640
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
We don't want to report errors on the internal contexts to userspace,
suppressing their own, so treat them as simulated errors. These mostly
arise inside selftests and so are simulated anyway. For the rest, we can
rely on the normal debug channels in CI.
