datapath: compat: unset skb encapsulation bit

OVS compat layer can handle tunnel GSO packets. but it does
keep skb encapsulation on for packet handled in GSO. This can
confuse some NIC drivers. I have seen this issue on intel devices:

>>>  i40e 0000:42:00.0: TX driver issue detected, PF reset issued

Following patch resets this bit in case compat layer handles the packet.
