Subject: libbpf: Fix error path in bpf_object__elf_init()
Patch-mainline: v5.12-rc5
Git-commit: 8f3f5792f2940c16ab63c614b26494c8689c9c1e
References: bsc#1177028

When it failed to get section names, it should call into
bpf_object__elf_finish() like others.

Fixes: 88a82120282b ("libbpf: Factor out common ELF operations and improve logging")
