Generate the correct prefix value for IPv4 netmasks 0.0.0.0

When the netmask is assigned the value 0.0.0.0 the prefix is 0, not
33. The algorithm generated an incorrect prefix value when the netmask
was set to 0.0.0.0.

Tested:
ipmitool lan set 3 ipsrc static

ipmitool lan set 3 ipaddr 192.168.20.12
Setting LAN IP Address to 192.168.20.12
