Fix invalid gateway toast message

Add check for gateway value before testing if the string is valid.
The backend seems to handle an empty gateway the same as sending
0.0.0.0. When the GET call is made after sending 0.0.0.0 as the
gateway value, the response returns an empty string. This field
seems to be an override for the default gateway input for the
interface.
