wifi-scripts: fix creation of IBSS in legacy (non-HT) mode

Browse Source 
When an IBBS interface is configured for IBSS legacy mode, wdev.htmode
is empty. This is empty string results in an empty positional argument
to the "ibbs join" command, for example:

    iw dev phy0-ibss0 ibss join crymesh 2412 '' fixed-freq beacon-interval 100

This empty argument is interpreted as an invalid HT mode by 'iw',
causing the entire command to fail and print a "usage" message:

    daemon.notice netifd: radio0 (4527): Usage:    iw [options] \
        dev <devname> ibss join <SSID> <freq in MHz> ...

Although nobody will ever need more than 640K of IBSS, explicitly use
"NOHT" if an HT mode is not given. This fixes the problem.
