Fix some multi-BSSID configuration operations

Static WEP keys were configured only for the first BSS. In addition,
STAs were flushed only for the first BSS. These operations should be in
hostapd_setup_bss(), not setup_interface().

Remove extra call to ieee802_11_set_beacon() for the first BSS. This
should only be done from hostapd_setup_bss(), i.e., once for each BSS.
