datapath: Fix STT packet receive handling.
STT reassembly can generate list of packets. But it was
handled as a single skb. Following patch fixes it.
Fixes: e23775f20 ("datapath: Add support for lwtunnel").

Log Message:
-----------
datapath: Backport: skbuff: Fix skb checksum partial check.
This bug fix is not required for OVS use cases. But is it
nice to keep function consistent with upstream implementation.
Upstream commit:
Earlier patch 6ae459bda tried to detect void ckecksum partial
skb by comparing pull length to checksum offset. But it does
not work for all cases since checksum-offset depends on
updates to skb->data.
Following patch fixes it by validating checksum start offset
after skb-data pointer is updated. Negative value of checksum
offset start means there is no need to checksum.
Fixes: 6ae459bda ("skbuff: Fix skb checksum flag on skb pull")
