[PATCH] cfg80211: update misleading comment

[Helmut Schaa <helmut.schaa@googlemail.com>]

In cfg80211_scan_request n_channels refers to the total number
of channels to scan. Update the misleading comment accordingly.

Maybe the comment is correct and it is just me who thinks it is
misleading ;) but I just stumbled over that.
