openvswitch: Add missing initialization in validate_and_copy_set_tun()
net/openvswitch/flow_netlink.c: In function ‘validate_and_copy_set_tun’: net/openvswitch/flow_netlink.c:1749: warning: ‘err’ may be used uninitialized in this function If ipv4_tun_from_nlattr() returns a different positive value than OVS_TUNNEL_KEY_ATTR_GENEVE_OPTS, err will be uninitialized, and validate_and_copy_set_tun() may return an undefined value instead of a zero success indicator. Initialize err to zero to fix this.
