Subject: [PATCH AUTOSEL 5.16 013/217] selftests/bpf: Destroy XDP link correctly

From: Sasha Levin <[email-masked]>
Date: Mon, 17 Jan 2022 21:16:16 -0500

From: Andrii Nakryiko <[email-masked]>

[ Upstream commit f91231eeeed752119f49eb6620cae44ec745a007 ]

bpf_link__detach() was confused with bpf_link__destroy() and leaves
leaked FD in the process. Fix the problem.
