net: sock_map, fix missing ulp check in sock hash case
sock_map and ULP only work together when ULP is loaded after the sock
map is loaded. In the sock_map case we added a check for this to fail
the load if ULP is already set. However, we missed the check on the
sock_hash side.
Add a ULP check to the sock_hash update path.
Fixes: 604326b41a6fb ("bpf, sockmap: convert to generic sk_msg interface")
