drm/i915: Hold gt_lock across forcewake register reads Along with the previous patch to make the reset operation protected by the gt_lock as well, this ensures that all register read operations will occur with the forcewake hardware enabled. As an added bonus, this makes read operations more efficient by taking the spinlock only once per read instead of twice.
