LinuxKPI: 802.11: adjust vif->bss_conf.chanctx_conf to rcu accessors
Adjust the init and lkpi_sta_scan_to_auth() chanctx_conf accesses to
use rcu functions as needed.
linuxkpi_ieee80211_iterate_chan_contexts() which is
ieee80211_iter_chan_contexts_atomic() needs further work to get rid
of the vif locks by keeping all chanctx_conf on a list in lhw.
This will be done in a follow-up commit.
