datapath: Copy Xen's checksumming fields when doing skb_copy.

Two fields that control checksumming were added to sk_buff in
Xen: proto_data_valid and proto_csum_blank.  These fields are copied
when doing a skb_clone but not in other functions such as skb_copy,
which can lead to checksum errors in TCP and UDP when offloading is
enabled in the guest.  To fix this we manually copy these fields,
though ideally this should be fixed upstream in Xen.

Bug #2299
