[PATCH linux-next] drm/amdgpu/vcn: Remove unused assignment in vcn_v4_0_stop

[Dong, Ruijing]

[AMD Official Use Only - General]

Sorry, which "r" value was overwritten?  I didn't see the point of making this change.

Thanks
Ruijing

The value assigned from vcn_v4_0_stop_dbg_mode to r is overwritten before it can be used. Remove this assignment.
