[PATCH 5.11 169/254] libbpf: Fix error path in bpf_object__elf_init()

[Greg Kroah-Hartman]

From: Namhyung Kim <namhyung@xxxxxxxxxx>

[ Upstream commit 8f3f5792f2940c16ab63c614b26494c8689c9c1e ]

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")
