net: Preserve CHECKSUM_COMPLETE at validation
Currently when the first checksum in a packet is validated using CHECKSUM_COMPLETE, ip_summed is overwritten to be CHECKSUM_UNNECESSARY so that any subsequent checksums in the packet are not correctly validated. This patch adds csum_valid flag in sk_buff and uses that to indicate validated checksum instead of setting CHECKSUM_UNNECESSARY. The bit is set accordingly in the skb_checksum_validate_* functions. The flag is checked in skb_checksum_complete, so that validation is communicated between checksum_init and checksum_complete sequence in TCP and UDP.
