drm/amd/display: Fix set scaling doesn's work

Browse Source 
[Why]
Setting scaling does not correctly update CRTC state. As a result
dc stream state's src (composition area) && dest (addressable area)
was not calculated as expected. This causes set scaling doesn's work.

[How]
Correctly update CRTC state when setting scaling property.
