net/mlx5e: Rely on filter_dev instead of dissector keys for tunnels
Currently, tunnel attributes are parsed and inner header matching is used only when flow dissector specifies match on some of the supported encapsulation fields. When user tries to offload tc filter that doesn't match any encapsulation fields on tunnel device, mlx5 tc layer incorrectly sets to match packet header keys on encap header (outer header) and firmware rejects the rule with syndrome 0x7e1579 when creating new flow group. Change __parse_cls_flower() to determine whether tunnel is used based on fitler_dev tunnel info, instead of determining it indirectly by checking flow dissector enc keys.
