dhcpv4: fix DHCP packet size

Calculate the DHCP packet size based on the number of DHCP options in the
message. Make sure the DHCP packet size does not go lower than 300 bytes
as some clients ignore DHCP messages smaller than 300 bytes.

Based on a patch by Dainis Jonitis <dainis.jonitis@ubnt.com>
