[PATCH] rndis_wlan: remove set_channel cfg80211 hook

[PATCH] rndis_wlan: remove set_channel cfg80211 hook

[Johannes Berg]

From: Johannes Berg <johannes.berg@intel.com>

Since rndis_wlan only supports managed and IBSS
modes, it doesn't need a set_channel call. The
callback might be called, but it won't matter
as nothing can use the channel.
