l2tp: don't mask errors in pppol2tp_setsockopt()
pppol2tp_setsockopt() unconditionally overwrites the error value returned by pppol2tp_tunnel_setsockopt() or pppol2tp_session_setsockopt(), thus hiding errors from userspace. Fixes: fd558d186df2 ("l2tp: Split pppol2tp patch into separate l2tp and ppp parts") Signed-off-by: Guillaume Nault <g.nault@alphalink.fr> Signed-off-by: David S. Miller <davem@davemloft.net>
