tipc: use only positive error codes in messages
In commit e3a77561e7d32 ("tipc: split up function tipc_msg_eval()"), we have updated the function tipc_msg_lookup_dest() to set the error codes to negative values at destination lookup failures. Thus when the function sets the error code to -TIPC_ERR_NO_NAME, its inserted into the 4 bit error field of the message header as 0xf instead of TIPC_ERR_NO_NAME (1). The value 0xf is an unknown error code. In this commit, we set only positive error code.
