bpf: sockmap, synchronize_rcu before free'ing map
We need to have a synchronize_rcu before free'ing the sockmap because
any outstanding psock references will have a pointer to the map and
when they use this could trigger a use after free.
Fixes: 604326b41a6fb ("bpf, sockmap: convert to generic sk_msg interface")
