AP BSSID configuration is missing at AP start.
Without this fix, FW returns STA interface MAC address after first init.
When hostapd restarts, it gets MAC address from netdev before driver
sets STA MAC to netdev again. Now MAC address between hostapd and net
interface are different causes STA cannot connect to AP.
After that MAC address of uap0 mlan0 become the same. And issue
disappears after following hostapd restart (another issue is AP/STA MAC
address become the same).
This patch fixes the issue cleanly.
