Tao Chen 4966cd0c09 bpf: Check link_create.flags parameter for multi_kprobe
[ Upstream commit 243911982a ]

The link_create.flags are currently not used for multi-kprobes, so return
-EINVAL if it is set, same as for other attach APIs.

We allow target_fd, on the other hand, to have an arbitrary value for
multi-kprobe, as there are existing users (libbpf) relying on this.
