This makes access to the STA hash table/list use RCU to protect against freeing of items. However, it's not a true RCU, the copy step is missing: whenever somebody changes a STA item it is simply updated. This is an existing race condition that is now somewhat understandable. This patch also fixes the race key freeing vs. STA destruction by making sure that sta_info_destroy() is always called under RTNL and frees the key.
