drm/i915: Drop stray clearing of rps->last_adj

Browse Source 
We used to reset last_adj to 0 on crossing a power domain boundary, to
slow down our rate of change. However, commit 60548c554b ("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.

Fixes: 60548c554b ("drm/i915: Interactive RPS mode")
Testcase: igt/pm_rps/mix-max-config-loaded
