ipv4: use IS_ENABLED instead of ifdef
Checking for ifdef CONFIG_x fails if CONFIG_x=m.
Use IS_ENABLED instead, which is true for both built-ins and modules.
Otherwise, a
> ip -4 route add 1.2.3.4/32 via inet6 fe80::2 dev eth1
fails with the message "Error: IPv6 support not enabled in kernel." if
CONFIG_IPV6 is `m`.
In the spirit of b8127113d01e53adba15b41aefd37b90ed83d631.
Fixes: d15662682db2 ("ipv4: Allow ipv6 gateway with ipv4 routes")
