A kfunc may be listed in several BTF ID sets, which is expected because different kfuncs are available to BPF programs depending on their type. However kfunc flags across different BTF ID sets must be consistent [1]. The flags should be considered a part of the kfunc declaration, because they influence its BTF representation and verifier handling. Enforce the kfunc flag consistency in resolve_btifds by hard failing on error and blocking kernel (or module) build.
