evaluate: remove table from cache on delete table

The following ruleset crashes nft if loaded twice, via nft -ef:

 add table inet filter
 delete table inet filter

 table inet filter {
        chain input {
                type filter hook input priority filter; policy drop;
                iifname { "eth0" } counter accept
        }
 }

If the table contains anonymous sets, such as __set0, then delete + add
table might result in nft reusing the existing stale __set0 in the cache.
The problem is that nft gets confused and it reuses the existing stale
__set0 instead of the new anonymous set __set0 with the same name.
