Add Framed-IP-Address to Accounting-Request if STA address is known

Browse source 
The recently added ProxyARP support (proxy_arp=1) in hostapd allows a
STA IPv4 address to be learned from DHCP or ARP messages. If that
information is available, add it to Account-Request messages in
Framed-IP-Address attribute.
