xfrm: remove xfrm_state_put_afinfo

Browse source

commit 44abdc3047
("xfrm: replace rwlock on xfrm_state_afinfo with rcu") made
xfrm_state_put_afinfo equivalent to rcu_read_unlock.

Use spatch to replace it with direct calls to rcu_read_unlock:

@@
struct xfrm_state_afinfo *a;
@@

-  xfrm_state_put_afinfo(a);
+  rcu_read_unlock();
