[PATCH] drm/amdgpu: Don't save new cursor size before updating CUR_SIZE register.

[Liviu Dudau]

Commit 7c83d7abc999 ("drm/amdgpu: Only update the CUR_SIZE register when
necessary") did not cleanup correctly the old code for DCE v6 and v8.
As a consequence, cursor updates stopped working for my Radeon R9 1002:67b0
dual-monitor setup.

Fixes: 7c83d7abc999 ("drm/amdgpu: Only update the CUR_SIZE register when necessary")
