net: checksum: Add IP header checksum calculation
At present net_checksum_calculate() only calculates TCP/UDP checksum in an IP packet, but assumes the IP header checksum to be provided by the software, e.g.: Linux kernel always calculates the IP header checksum. However this might not always be the case, e.g.: for an IP checksum offload enabled stack like VxWorks, the IP header checksum can be zero. This adds the checksum calculation of the IP header.
