wifi: mac80211: add and use chanctx usage iteration

In preparation for NAN interfaces using multiple channel
contexts, add an iterator macro that iterates all users
of a given channel context.

The logic during reserved assign/reassign handling the
bandwidth in ieee80211_get_chanctx_max_required_bw() is
a bit more complicated and should be cleaned up, so it
isn't yet converted.
