[PATCH 5.16 0552/1039] selftests/bpf: Fix bpf_object leak in skb_ctx selftest

[Greg Kroah-Hartman]

From: Andrii Nakryiko <andrii@xxxxxxxxxx>

[ Upstream commit 8c7a95520184b6677ca6075e12df9c208d57d088 ]

skb_ctx selftest didn't close bpf_object implicitly allocated by
bpf_prog_test_load() helper. Fix the problem by explicitly calling
bpf_object__close() at the end of the test.
