mac80211: Fix one more call to synchronize_rcu in atomic context.
(This set applies OK without the previous one of 4 patches, but with some fuzz in the 7th one) The mesh_path_node_free() does so under hashwlock. But, this one is called 1. from mesh_path_add() after an old hash is hidden and synchronize_rcu() is calld 2. mesh_pathtbl_unregister(), when the module is being unloaded and no devices exist to mess with this hash. So, it seems to me, that simply removing the call is OK. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
