3.4-stable review patch. If anyone has any objections, please let me know.

From: Gao feng <gaof...@cn.fujitsu.com>
[ Upstream commit 08252b32311c3fa84219ad794d640af7399b5485 ]
pptp always use init_net as the net namespace to lookup
route, this will cause route lookup failed in container.
because we already set the correct net namespace to struct
sock in pptp_create,so fix this by using sock_net(sk) to
replace &init_net.
