cfg80211: add channel tracking for AP and mesh
We need to know which channel is used by a running
AP and mesh for channel context accounting and
finding matching/active interface combination.
STA/IBSS have current_bss already which allows us
to check which channel a vif is tuned to.
Non-fixed channel IBSS can be handled with
additional changes.
Monitor mode is going to be handled differently.
