iwlwifi: clear all the stop_queue flag after load firmware

commit a9e10fb9b1c6ad16e73cf2656951fce3a817611e upstream.

All the queues are awake and ready to use after loading firmware,
for firmware reload case, if any queues was stopped before
reload, mac80211 will wake those queues after restart hardware, so make
sure all the flag used to keep track of the queue status are
reset correctly.
