Revert "clatd: Use the TUN_NOCHECKSUM flag for the tun device"

This reverts commit 7efed4e30259da5348c4a7c2c77a0d0d4b13834d.

This change may bypass checksum validation for all packets even if
they have not been validated earlier.

Hardware supports checksum offload for IPv4 / IPv6 UDP and TCP
packets only. ICMPv4 / ICMPv6 / fragmented packet checksum offload
is not supported and as a result the checksum will not be validated
even once before these packet are delivered to the application.
