[PATCH nft] evaluate: incorrect byteorder with typeof and integer_datatype

[Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>]

 table bridge t {
         set s3 {
                 typeof meta ibrpvid
                 elements = { 2, 3, 103 }
         }
 }

 # nft --debug=netlink -f test.nft
 s3 t 0
 s3 t 0
        element 00000100  : 0 [end]     element 00000200  : 0 [end]     element 00000300  : 0 [end]
                ^^^^^^^^

The integer_type uses BYTEORDER_INVALID byteorder (which is implicitly
handled as BYTEORDER_BIG_ENDIAN).
