pptp: fix stack info leak in pptp_getname()
[ Upstream commit a5f6fc28d6e6cc379c6839f21820e62262419584 ]
pptp_getname() only partially initializes the stack variable sa,
particularly only fills the pptp part of the sa_addr union. The code
thereby discloses 16 bytes of kernel stack memory via getsockname().
Fix this by memset(0)'ing the union before.
