ip_gre: clear feature flags when incompatible o_flags are set
Commit dd9d598c6657 ("ip_gre: add the support for i/o_flags update via
netlink") added the ability to change o_flags, but missed that the
GSO/LLTX features are disabled by default, and only enabled some gre
features are unused. Thus we also need to disable the GSO/LLTX features
on the device when the TUNNEL_SEQ or TUNNEL_CSUM flags are set.
These two examples should result in the same features being set:
ip link add gre_none type gre local 192.168.0.10 remote 192.168.0.20 ttl 255 key 0
ip link set gre_none type gre seq
ip link add gre_seq type gre local 192.168.0.10 remote 192.168.0.20 ttl 255 key 1 seq
