Yuan Chen 1197abb1ee libbpf: Fix null pointer dereference in btf_dump__free on allocation failure
[ Upstream commit aa485e8789 ]

When btf_dump__new() fails to allocate memory for the internal hashmap
(btf_dump->type_names), it returns an error code. However, the cleanup
function btf_dump__free() does not check if btf_dump->type_names is NULL
before attempting to free it. This leads to a null pointer dereference
when btf_dump__free() is called on a btf_dump object.
