    LinuxKPI: 802.11: adjust locking around lkpi_remove_chanctx()

    With the adjusted locking as a first step and the single code path
    into lkpi_80211_mo_unassign_vif_chanctx() we also move the "setting
    chnactx to NULL" into the caller to simplify the code.

    Before we can adjust the other places touching vif->bss_conf.chanctx
    we need to adjust the overall locking in LinuxKPI 802.11.
