This is a bug revealed in r41830.
First, the static variable `char nif[IFNAMSIZ]` of nl80211_phy2ifname()
would be zeroed out if the argument is "wlan0" or the like. This will
happen in the following call stack.
nl80211_get_scanlist("radio0", buf, len);
nl80211_phy2ifname("radio0") // return static var nif with content "wlan0"
nl80211_get_scanlist(nif, buf, len); // tail call
nl80211_get_mode(nif);
nl80211_phy2ifname(nif); // zero out nif
Later we try nl80211_ifadd("") which was supposed to create interface
"tmp.", but that won't happen because nl80211_msg() will put an invalid
ifidx 0 to the nlmsg.
Then iwinfo_ifup() and iwinfo_ifdown() would fail and happily
nl80211_get_scanlist() returned 0 and left *len undefined.

There are several cases within 'luci' that attempt to access the interface
'type' from within the 'type' specific meta tables; however, 'type' is not
currently available there. Replicate the common metadata in the 'type'
specific meta tables.
