From: Hou Tao <houtao1@huawei.com>

There is an out-of-bounds read in bpf_link_show_fdinfo() for the sockmap
link fd. Fix it by adding the missing BPF_LINK_TYPE invocation for
sockmap link

Also add comments for bpf_link_type to prevent missing updates in the
future.

Fixes: 699c23f02c65 ("bpf: Add bpf_link support for sk_msg and sk_skb progs")
