[RFC 2/5] drm/xe: Trigger a devcoredump capture on a GT reset

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

The GT reset code does not have access to a scheduler job, and is
usually called from some error condition disconnected from the job
submisson flow. Hence it did not generate a devcoredump. However,
devcoredumps can now be triggered without a job, so do so.
