netlink: Lockless lookup with RCU grace period in socket release
Defers the release of the socket reference using call_rcu() to allow using an RCU read-side protected call to rhashtable_lookup() This restores behaviour and performance gains as previously introduced by e341694 ("netlink: Convert netlink_lookup() to use RCU protected hash table") without the side effect of severely delayed socket destruction.
