This removes one of the two sources of device restarts in the upper layer -- those are a bit inconvenient because normal restarts originate in the transport. By moving the watchdog down it can be treated the same. Also rewrite the watchdog logic. Timers are much more efficient when they never fire, so instead firing a timer every 500ms set up a timer for each TX queue and fire it only when the queue is really stuck. This avoids the CPU waking up when everything is working well. While at it, remove the wd_disable config item and replace it by simply setting wd_timeout to IWL_WATCHHDOG_DISABLED (0).
