selftests/bpf: libarena: Clean up allocation state before buddy tests

Browse source

Summary: The buddy allocator requires the global BPF buddy allocator
to not be already initialized. However, the test currently merely resets
the allocator before the buddy tests instead of destroying it, and the
test worked because the buddy test happened to run first. Properly
destroy the allocator instead of resetting it.
