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.
