    iwlwifi: avoid Tx queue memory allocation in interface down
    
    We used to free all the Tx queues memory when interface is brought
    down and reallocate them again in interface up. This requires
    order-4 allocation for txq->cmd[]. In situations like s2ram, this
    usually leads to allocation failure in the memory subsystem. The
    patch fixed this problem by allocating the Tx queues memory only at
    the first time. Later iwl_down/iwl_up only initialize but don't
    free and reallocate them. The memory is freed at the device removal
    time. BTW, we have already done this for the Rx queue.
