DHCP: Ensure we have enough data to checksum IP and UDP

While here, only skip UDP checksum after we have verified we
have enough data to be doubly sure.

Fixes a regression introduced in dhcpcd-7.2.0 when we started
to read from the UDP socket rather than just the BPF socket
where these checks are already made.
