Remove failed deserialization error message (#399)

Firstly, a failure in deserialization for a network message is not
an error especially since we're using a public channel.
Secondly, that same channel is shared by different kind of messages
so trying to interpret one as the other will surely lead to a
unsuccessfull attempt.
