[Intel-gfx] [PATCH i-g-t] i915/i915_hangman: Drop last reference to bygone 'i915_error_state'

[Chris Wilson]

The test is looking at sysfs/error so dumping the old
debugfs/i915_error_state looks quite silly. The only dilemma is whether
it is worth replacing with a line-by-line dump. I propose we make that a
future problem -- and leave it to whoever has to debug it next time.
