drm/amd/display: Fix dc_sink kref count in emulated_link_detect
[ Upstream commit 3ddc818d9bb877c64f5c649beab97af86c403702 ]
[why]
prev_sink is not used anywhere else in the function and the reference to
it from dc_link is replaced with a new dc_sink.
[how]
Change dc_sink_retain(prev_sink) to dc_sink_release(prev_sink).
