[PATCH] mac80211: fix set_channel regression

Adam Baker reported that the prism2 ioctl removal changed behaviour
in that now the selection order was the other way around as before.
New API is planned but not done yet, so for now just use the first
matching channel in any mode as was previous behaviour with an unset
next_mode.
