[Intel-gfx] [PATCH] drm/i915/gt: Ignore error capturing a closed context

[Chris Wilson]

Quoting Chris Wilson (2021-01-29 12:06:20)
> To capture a context after a gpu hang, we suspend the request and then
> resume its execution afterwards. If the context is already closed, we
> can assume that no one is interested in the result, but instead we are
> trying to terminate execution quickly as part of a forced-preemption.
> In which case, do not waste time in suspending the request, capturing
> the error, and just cancel it instead.
