Don't req a clone-able ChannelManager in LSPS2ServiceHandler

`LSPS2ServiceHandler` currently requires that the `Deref` to a
`ChannelManager` be `Clone`, but doesn't use it for anything. This
upsets the bindings somewhat as they generate a wrapper struct
which implements `Deref` (as it holds a pointer) but does not
implement `Clone` (as the inner object cannot be cloned.

Thus, we simply remove the additional bound here.
