LinuxKPI: 802.11: add a lchanctx list to lhw
While we are currently only supporting a single VAP (vif) it is
less of a trouble but in order to get locking and rcu accesses
[from drivers] more right add a list for all chanctx_conf we have
for one hw. Use that list in the iterator function to avoid
having to lock the vif but not protecting the chanctx list
(against a parallel removal) due to different locking.
