attach query counter to NS fetches

Browse source 
there were cases in resolver.c when queries for NS records were
started without passing a pointer to the parent fetch's query counter;
as a result, the max-recursion-queries quota for those queries started
counting from zero, instead of sharing the limit for the parent fetch,
making the quota ineffective in some cases.
