[ Upstream commit a21ab4c59e ]
If creating an outer map of a BTF-defined map-in-map fails (via
bpf_object__create_map()), then the previously created its inner map
won't be destroyed.
Fix this by ensuring that the destroy routines are not bypassed in the
case of a failure.
Fixes: 646f02ffdd ("libbpf: Add BTF-defined map-in-map support")
