htlcswitch: change ForwardPackets to return error

Browse Source 
As part of the preparation to the switch interceptor feature, this
function is changed  to return error instead of error channel that
is closed automatically.
Returning an error channel has become complex to maintain and
implement when adding more asynchronous flows to the switch.
The change doesn't affect the current behavior which logs the
errors as before.
