datapath: Consistently maintain checksum offloading state.
		
When adding a VLAN tag it is necessary for us to setup checksum
pointers for offloaded packets manually.  However, this process
clobbers some of the fields that other components need to determine
the current status.  Here we mark the packet with its status upon
ingress in our own format that does not get clobbered and is
consistent across kernel versions.

Bug #2436
