[Intel-gfx] [PATCH] drm/i915: Remove pointer indirection for hangcheck_state local

[Chris Wilson]

Use the local on-stack struct directly rather than hide it behind a
pointer. This should be both clearer for the reader and the compiler (we
rely on the compiler seeing through the functions to spot uninitialized
uses of the local).
