MINOR: quic: Wrong packet number space selection

Browse Source 
It is possible that the listener is in INITIAL state, but have to probe
with Handshake packets. In this case, when entering qc_prep_pkts() there
is nothing to do. We must select the next packet number space (or encryption
level) to be able to probe with such packet type.
