drm/amd/display: add protection in link encoder matching logic
[Why]
Link encoders are created based on its engine ID. The position of a link
encoder in an array could be null since it didn't be allocated. Current
matching logic didn't consider this situation and could get null
encoder.
[How]
To add null encoder check to make the matching logic can go to next to
get a valid one.
