Fix pppol2tp getsockname()
[ Upstream commit bbdb32cb5b73597386913d052165423b9d736145 ]
While testing L2TP functionality, I came across a bug in getsockname(). The
IP address returned within the pppol2tp_addr's addr memember was not being
set to the IP address in use. This bug is caused by using inet_sk() on the
wrong socket (the L2TP socket rather than the underlying UDP socket), and was
likely introduced during the addition of L2TPv3 support.
