openvswitch: switch from WARN to pr_warn
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.
