evaluate: do not pass EXPR_SET_ELEM to stmt_evaluate_arg() for set/map evaluation

Otherwise, we cannot validate mismatching length size when combining raw
expressions with sets and maps, eg.

 # cat /tmp/test
 table ip nftlb {
       map persistency {
               type ipv4_addr : mark
               size 65535
               timeout 1h
       }

       chain pre {
               type filter hook prerouting priority filter; policy accept;
               ip protocol { tcp, udp } update @persistency { @th,0,16 : numgen inc mod 2 offset 100 }
       }
 }

 # nft -f /tmp/test
 /tmp/test:10:68-75: Error: datatype mismatch: expected IPv4 address, expression has type integer with length 16
                    ip protocol { tcp, udp } update @persistency { @th,0,16 : numgen inc mod 2 offset 100 }
                                             ~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Pass inner expression instead, instead of the wrapping set element
expression.
