MINOR: quic: adjust quic_conn refcount decrement

Adjust slightly refcount code decrement on quic_conn close. A new
function named quic_conn_release is implemented. This function is
responsible to remove the quic_conn from CIDs trees and decrement the
refcount to free the quic_conn once all threads have finished to work
with it.

For now, quic_close is responsible to call it so the quic_conn is
scheduled to be free by upper layers. In the future, it may be useful to
delay it to be able to send remaining data or waiting for missing ACKs
for example.

This simplify quic_conn_drop which do not require the lock anymore.
Also, this can help to free the connection more quickly in some cases.
