We split channel state to a separate structure. This makes it easier to
wrap functions around channel operations alone without worrying whether
it's comming from ieee80211_local or ieee80211_sub_if_data.
Later a function: ieee80211_get_channel_state(local, sdata) would be
introduced to proxy access to appropriate ieee80211_channel_state
structure.
