BUG/MINOR: mux-h1: Fix conn_mode processing for headerless outgoing messages

Condition to process the connection mode on outgoing messages whithout
'Connection' header was wrong. It relied on the wrong H1M
state. H1_MSG_HDR_L2_LWS is only a possible state for messages with at least one
header. Now, to fix the bug, we just check the H1M state is not
H1_MSG_LAST_LF. So, we have the warranty the EOH was not processed yet.
