wifi: mwifiex: configure BSSID consistently when starting AP

wifi: mwifiex: configure BSSID consistently when starting AP

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.
