Summary

It turned out thare various calls into (*iv_update_bss)(), that is
direct changes to vap->iv_bss in the old days, happened without
synchronisation.

Use locking assertions to document the requirement or status quo
at some callers given ic locking will eventually have to be dealt
with.

By the way, I forgot to ask, is it also helpful to add IEEE80211_LOCK_ASSERT in lkpi_iv_update_bss()?
