"/sbin/wifi up" makes three ubus calls:
1. ubus call network reload
2. ubus call network.wireless down
3. ubus call network.wireless up
The first and third ubus calls call drv_mac80211_setup,
while the second ubus call triggers wireless_device_setup_cancel,
so the call sequence becomes,
1. drv_mac80211_setup
2. wireless_device_setup_cancel
3. drv_mac80211_setup
This commit swaps the order of the first two ubus calls,
1. ubus call network.wireless down
2. ubus call network reload
3. ubus call network.wireless up
Consequently drv_mac80211_setup is only called once,
and two related bugs (#FS3784 and #FS3902) are no longer triggered
by /sbin/wifi.
