MINOR: quic-be: qc_send_mux() adaptation for 0-RTT

Browse Source 
When entering this function, a selection is done about the encryption level
to be used to send data. For a client, the early data encryption level
is used to send 0-RTT if this encryption level is initialized.

The Initial encryption is also registered to the send list for clients if there
is Initial crypto data to send. This allow Initial and 0-RTT packets to
be coalesced by datagrams.
