Add a bpf_check_basics_ok() and reject filters that are of invalid size much earlier, so we don't do any useless work such as invoking bpf_prog_alloc(). Currently, rejection happens in bpf_check_classic() only, but it's really unnecessarily late and they should be rejected at earliest point. While at it, also clean up one bpf_prog_size() to make it consistent with the remaining invocations. Signed-off-by:
