The l2cap_recv_frame function is expected to take ownership and eventually free the skb passed to it. We need to ensure that the conn->rx_skb pointer is no longer reachable when calling l2cap_recv_frame so that no other function, such as l2cap_conn_del, may think that it can free conn->rx_skb. An actual situation when this can happen is when smp_sig_channel (called from l2cap_recv_frame) fails and l2cap_conn_del gets called as a consequence. The l2cap_conn_del function would then try to free conn->rx_skb, but as the same skb was just passed to smp_sig_channel and freed we get a double-free.
