Fix Validate default gateway

Prior to this patch we did't have any code in place to validate
the given dafault gateway.
We need to support multiple default gateways to support dual
stack(ipv4/ipv6).
Currently we only supports ipv4 so here we validate gw only for ipv4.
Opened new issue: https://github.com/openbmc/openbmc/issues/2570 to
support ipv6.

Resolves openbmc/openbmc#2520
