  Fix a mutex LOR introduced by the conversion of if_ndis from spinlocks to
  mutexes and replacing the obsolete if_watchdog interface. The ndis_ticktask
  function calls into ieee80211_new_state under one condition with NDIS_LOCK
  held. The ieee80211_new_state would call into ndis_start in some cases too,
  resulting in the occasional case where ndis_start acquires NDIS_LOCK from
  inside the NDIS_LOCK held by ndis_ticktask.
