[PATCH v3] mac80211: Call commit() on channel setting

["Alina Friedrichsen" <x-alina@gmx.net>]

This calls commit() on all logical interfaces of a physical interface, =
if the channel of it is changed. Before it works as it should, I must f=
ix the joining process of STA and IBSS a little, which I will make tomo=
rrow.

This version call it only in the wireless extensions, because the handl=
ing in nl80211 must discussed more, but I think in the case of wext it =
is the right way.
