Subject: [RFC PATCH net-next 2/5] selftests: mlxsw: sch_red_core: Use defer for test cleanup
Instead of having a suite of dedicated cleanup functions, use the defer
framework to schedule cleanups right as their setup functions are run.
This makes a dedicated cleanup() moot, instead fall back to the
lib.sh-provided one, which invokes the necessary defer cleanups as well.
