evaluate: fix mapping evaluation

 # cat ruleset.file
 table ip mangle {
        map CLASS05 {
                type ipv4_addr : mark
                elements = { 192.168.0.10 : 0x00000001}
        }

        chain OUTPUT {
                type route hook output priority 0; policy accept;
                mark set ip saddr map @CLASS05
        }
 }
 # nft -f ruleset.file
 ruleset.file:4:28-54: Error: mapping outside of map context
                elements = { 192.168.0.10 : 0x00000001}
                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^

This actually is fixing two problems:

1) Validate datatype of the rhs before evaluating the map definition,
   this is also setting set->datalen which is needed for the element
   evaluation.

2) Add missing set context.
