net/mlx5: update GENEVE TLV option matching

The GENEVE TLV option matching is done using a flex parser.

Recent update in firmware, requires that in order to match on the
GENEVE TLV option the "geneve_tlv_option_0_exist" bit should be set.

Add the new "geneve_tlv_option_0_exist" setting when translating the
GENEVE TLV option item.
