[ Upstream commit f2bde8349c35d01d7c50456ea06a5c7d5e0e5ed0 ]
[Why] A porting error resulted in the stream assignment for the link being retained without being released - a memory leak.
[How] Fix the porting error by adding back the dc_stream_release() intended as part of the original patch.
Fixes: 0bb245558584 ("drm/amd/display: retain/release at proper places in link_enc assignment")
