Andrei Vagin 62de3fe46c net/unix: don't show information about sockets from other namespaces ...

[ Upstream commit 0f5da659d8f1810f44de14acf2c80cd6499623a0 ]

socket_diag shows information only about sockets from a namespace where
a diag socket lives.

But if we request information about one unix socket, the kernel don't
check that its netns is matched with a diag socket namespace, so any
user can get information about any unix socket in a system. This looks
like a bug.

v2: add a Fixes tag
