camerabin: Correctly relink viewfinderbin_queue
This reverts a part of de92a6c7. Unlike image_filter
and
video_filter
, viewfinder_filter
does not get linked to src
but
viewfinderbin_queue
. Thus the fix in the mentioned commit does not
apply for it and should be reverted.
This was not spotted earlier as only the other filters are used in the project that uncovered the issue.
