mac80211: Deactivate mesh path timers when freeing nodes
Javier Cardona [Fri, 13 May 2011 21:16:07 +0000 (14:16 -0700)]
Mesh paths are deleted via mesh_path_del() which properly
deactivates the timer associated to a mesh path.  But if paths were
deleted by mesh_table_free(..., true) timers would not be deactivated.
This fixes this case.
