Although a banned context will be told to -EIO off if they try to submit
more requests, we have a discrepancy between whole device resets and
per-engine resets where we report the GPU reset but not the engine
resets. This leaves a bit of mystery as to why the context was banned,
and also reduces awareness overall of when a GPU (engine) reset occurs
with its possible side-effects.
