[OpenWrt-Devel] fix typo in netifd.sh

$ht variable is not passed. $htmode is.

With this, wpa_supplicant-phy0.conf contains htmode line if htmode is set in config.

this patch is wrong for the following reasons

* the htmode values inside netifd-wireless.sh are not the same values
that wpa_supplicant expects
* wpa_supplicant should automagically detect the channel (and the HT40
ext chan)

this leads me to wonder why you need this and an option would be 2 adhoc
clients.

can you explain your wifi setup so that we can figure out how to
properly fix this ?

config wifi-device 'radio1'
	option type 'mac80211'
	option hwmode '11a'
	option path 'pci0000:00/0000:00:00.0'
	option disabled '0'
	option htmode 'HT20'
	option channel '48'

config wifi-iface
	option device 'radio1'
	option encryption 'psk2'
	option key '1234567890'
	option network 'wlan'
	option mode 'adhoc'
	option ssid 'link-5g'

Without patch I've got

root@OpenWrt:~# cat /var/run/wpa_supplicant-wlan1.conf 
ap_scan=2
network={
	scan_ssid=0
	ssid="link-5g"
	key_mgmt=WPA-PSK
	mode=1
	fixed_freq=1
	frequency=5240
	mode=1
	psk="1234567890"
	proto=RSN
}

iw wlan1 info shows only 20 MHz (no HT) and iw wlan1 station dump - tx/rx 54MBit

With patch:

root@OpenWrt:~# cat /var/run/wpa_supplicant-wlan1.conf 
ap_scan=2
network={
	scan_ssid=0
	ssid="link-5g"
	key_mgmt=WPA-PSK
	mode=1
	fixed_freq=1
	frequency=5240
	mode=1
	psk="1234567890"
	proto=RSN
	htmode=HT20
}

iw wlan1 info shows channel 48 (5240 MHz), width: 20 MHz, center1: 5240 MHz 
(width: 40 MHz with channel 36 and HT40+); iw wlan1 station dump shows
bitrate

rx bitrate:	115.6 MBit/s MCS 13 short GI
tx bitrate:	57.8 MBit/s MCS 5 short GI
rx bitrate:	86.7 MBit/s MCS 12 short GI

etc.

ok, so it is adhoc mode. in this case the feature does make sense. the
problem is that the values provided by netifd-wireless.sh cannot
directly be translated to wpa_supplicant values. additionally yor patch
should ensure that values are only applied for adhoc networks. i will
put this on my list and investigate a bit further.

I have added a proper fix for this issue in r44100
