[RFC PATCH bpf-next v7 03/11] libbpf: fix return value on memory allocation failure

[Hui Zhu]

From: Roman Gushchin <roman.gushc...@linux.dev>

bpf_map__attach_struct_ops() returns -EINVAL instead of -ENOMEM
on the memory allocation failure. Fix it.

Fixes: 590a00888250 ("bpf: libbpf: Add STRUCT_OPS support")
