drm/i915: Drop stray clearing of rps->last_adj
We used to reset last_adj to 0 on crossing a power domain boundary, to slow down our rate of change. However, commit 60548c554be2 ("drm/i915: Interactive RPS mode") accidentally caused it to be reset on every frequency update, nerfing the fast response granted by the slow start algorithm.
