seccomp: ignore secure_computing return values
This change is inspired by
https://lkml.org/lkml/2012/4/16/14
which fixes the build warnings for arches that don't support
CONFIG_HAVE_ARCH_SECCOMP_FILTER.
In particular, there is no requirement for the return value of
secure_computing() to be checked unless the architecture supports
seccomp filter. Instead of silencing the warnings with (void)
a new static inline is added to encode the expected behavior
in a compiler and human friendly way.
v2: - cleans things up with a static inline
- removes sfr's signed-off-by since it is a different approach
v1: - matches sfr's original change
