net: tipc: fix information leak to userland

commit 88f8a5e3e7defccd3925cabb1ee4d3994e5cdb52 upstream.

Structure sockaddr_tipc is copied to userland with padding bytes after
"id" field in union field "name" unitialized.  It leads to leaking of
contents of kernel stack memory.  We have to initialize them to zero.
