[PATCH net-next] selftests: net: reuseport_addr_any: silence clang warning

From: Peter Oskolkov <hidden>
Date: 2018-12-21 00:29:56
Subsystem: kernel selftest framework, networking [general], the rest · Maintainers: Shuah Khan, Shuah Khan, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

Clang does not recognize that calls to error() terminate execution
and complains about uninitialized variable use that happens after calls
to error(). This noop patchset fixes this.
