batman-adv: Avoid double freeing of bat_counters
On errors in batadv_mesh_init(), bat_counters will be freed in both batadv_mesh_free() and batadv_softif_init_late(). This patch fixes this by returning earlier from batadv_softif_init_late() in case of errors in batadv_mesh_init() and by setting bat_counters to NULL after freeing.
