Guillaume Nault 02c2d9e72e l2tp: lock socket before checking flags in connect() 
commit 0382a25af3c771a8e4d5e417d1834cbe28c2aaac upstream.

Socket flags aren't updated atomically, so the socket must be locked
while reading the SOCK_ZAPPED flag.

This issue exists for both l2tp_ip and l2tp_ip6. For IPv6, this patch
also brings error handling for __ip6_datagram_connect() failures.
