openvswitch: switch from WARN to pr_warn
[ Upstream commit fd954cc1919e35cb92f78671cab6e42d661945a3 ]
As noted by Paolo Abeni, pr_warn doesn't generate any splat and can still
preserve the warning to the user that feature downgrade occurred. We
likely cannot introduce other kinds of checks / enforcement here because
syzbot can generate different genl versions to the datapath.
