mac80211: pass channel to ieee80211_send_probe_req
In multi-channel scenarios, the channel that we will transmit a probe request on isn't always the current channel (which will be NULL anyway) but will instead be the channel that the AP is on. Pass the channel to the ieee80211_send_probe_req() function so it can be used in the different scenarios. The scan code continues to pass the current channel, of course.
