MINOR: quic: Wrong packet refcount handling in qc_pkt_insert()

The QUIC connection I/O handler qc_conn_io_cb() could be called just after
qc_pkt_insert() have inserted a packet in a its tree, and before qc_pkt_insert()
have incremented the reference counter to this packet. As qc_conn_io_cb()
decrement this counter, the packet could be released before qc_pkt_insert()
might increment the counter, leading to possible crashes when trying to do so.
So, let's make qc_pkt_insert() increment this counter before inserting the packet
it is tree. No need to lock anything for that.
