[PATCH 4.9 105/134] seccomp: Add missing return in non-void function

[Greg Kroah-Hartman]

From: Paul Cercueil <p...@crapouillou.net>

commit 04b38d012556199ba4c31195940160e0c44c64f0 upstream.

We don't actually care about the value, since the kernel will panic
before that; but a value should nonetheless be returned, otherwise the
compiler will complain.

Fixes: 8112c4f140fa ("seccomp: remove 2-phase API")
