iwlwifi: mvm: don't send identical PHY_CTXT_CMD
When we have an AP which supports HT and a single HT station is connected, we change the min_width from NL80211_CHAN_WIDTH_20_NOHT to NL80211_CHAN_WIDTH_20. This of course has no implication on the channel width but still sends a command to the firmware. Remember the last width that was sent and refrain from sending unnecessary commands to the firmware. Sending a PHY_CTXT_CMD to the firmware has a cost since it recalculates the presence on the medium and because of that it closes the transmit queues for a short while.
