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.
