[PATCH RFC 3/9] drm/i915: Avoid open-coded use of ratelimit_state structure's ->missed field

[Paul E. McKenney]

The i915_oa_stream_destroy() function directly accesses the
ratelimit_state structure's ->missed field, which work, but which also
makes it more difficult to change this field.  Therefore, make use of
the ratelimit_state_get_miss() function instead of directly accessing
the ->missed field.
