Subject: [PATCH net-next 12/15] selftests: devlink_lib: Split out helper

From: Ido Schimmel <idosch@...dia.com>

Merely checking whether a trap counter incremented or not without
logging a test result is useful on its own. Split this functionality to
a helper which will be used by subsequent patches.
