Resolver: fixed debug event logging. In 954867a2f0a6, we switched to using resolver node as the timer event data. This broke debug event logging. Replaced now unused ngx_resolver_ctx_t.ident with ngx_resolver_node_t.ident so that ngx_event_ident() extracts something sensible when accessing ngx_resolver_node_t as ngx_connection_t.
