l2tp: check sockaddr length in pppol2tp_connect()
[ Upstream commit eb1c28c05894a4b1f6b56c5bf072205e64cfa280 ]
Check sockaddr_len before dereferencing sp->sa_protocol, to ensure that
it actually points to valid data.
Fixes: fd558d186df2 ("l2tp: Split pppol2tp patch into separate l2tp and ppp parts")
