The presence of a channel capability is checked against the tb_msg
netlink attributes array which is the root one, while here we are
looking for channel capabilities, themselves being nested and parsed
into tb_caps. Use tb_caps instead of tb_msg here otherwise we are
accessing a random index in the upper attributes list.
