[PATCH] cfg80211: fix WEXT ioctl GIWFREQ for monitor interfaces

[David Gnedt <david.gnedt@davizone.at>]

The cfg80211_set_freq function now also saves the channel for monitor
interfaces.
This fixes a issue were the WEXT ioctl GIWFREQ doesn't report the correct
channel when the channel was switched in monitor mode.
