l2tp: Remove redundant BUG_ON() check in l2tp_pernet
Passing NULL to l2tp_pernet causes a crash via BUG_ON. Dereferencing net in net_generic() also has the same effect. This patch removes the redundant BUG_ON check on the same parameter. Signed-off-by: Xu Wang <vulab@iscas.ac.cn> Signed-off-by: David S. Miller <davem@davemloft.net>
