dccp: check ccid before dereferencing
commit 276bdb82dedb290511467a5a4fdbe9f0b52dce6f upstream.
ccid_hc_rx_getsockopt() and ccid_hc_tx_getsockopt() might be called with
a NULL ccid pointer leading to a NULL pointer dereference. This could
lead to a privilege escalation if the attacker is able to map page 0 and
prepare it with a fake ccid_ops pointer.
