iwlwifi: fix DMA channel number in iwl_txq_ctx_stop
The patch fixes the misuse of DMA channel number by Tx queue number in
iwl_tx_ctx_stop().
The problem was originally reported by Wu Fengguang who complains
iwlagn driver takes too long time when issuing `ifconfig wlan0 down`.
The patch now decreases the interface bring down time from 2 seconds
to 0.8 second.
This fixes bugs:
