Subject: geneve: fix incorrect setting of UDP checksum flag

From: Girish Moodalbail <girish.moodalbail@oracle.com>


[ Upstream commit 5e0740c445e6ae4026f5e52456ff8d0be9725183 ]

Creating a geneve link with 'udpcsum' set results in a creation of link
for which UDP checksum will NOT be computed on outbound packets, as can
be seen below.

11: gen0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN
    link/ether c2:85:27:b6:b4:15 brd ff:ff:ff:ff:ff:ff promiscuity 0
    geneve id 200 remote 192.168.13.1 dstport 6081 noudpcsum

Similarly, creating a link with 'noudpcsum' set results in a creation
of link for which UDP checksum will be computed on outbound packets.
