quic: return 0 from SSL_CTX_sess_set_new_cb callback

The callback passed to `SSL_CTX_sess_set_new_cb()` should return 1
if it takes ownership (i.e. holds a reference that is later freed
through `SSL_SESSION_free()`) of the passed session, and 0
otherwise.

Since we don’t take ownership of the session and instead only save
a serialized version of it, return 0 instead of 1. This closes
a memory leak reported when running
`sequential/test-quic-preferred-address-ipv6`.
