Devices can't add a device with a Static IP address outside of dyanmic/static range

When trying to add a device with an IP address that falls outside the static or dynamic range, the "save device' was not clickable on some cases, and the device could not be added.

IP address was 192.168.10.9

When trying to add the device with 192.168.10.6 it worked just fine.

MAAS Dynamic range goes from: 10.10 to 10.100
and Static from 10.101 to 10.254.
