[PATCH 2/3] Handle reference for RedPipeItem in RedChannel

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

Remove the need to release the item inside send_item callbacks.
This looks like a partial rollback of previous patch but is
to make clear the intention of the change.
The lifetime of items could extend a bit further but there
are no cases this small lag should cause problems.
