Mark Johnston e62e4b8594 ng_l2tp: Fix callout synchronization in the rexmit timeout handler ... A received control packet may cause the transmit queue to be flushed, in which case ng_l2tp_seq_recv_nr() cancels the transmit timeout handler. The handler checks to see if it was cancelled before doing anything, but did so before acquiring the node lock, so a small race window could cause ng_l2tp_seq_rack_timeout() to attempt to flush an empty queue, ultimately causing a null pointer dereference.
