Avoid extra snprintf() in dsl_deadlist_merge().
Since we are already iterating the ZAP, we have exact string key to
remove, we do not need to call zap_remove_int() with the int key we
just converted, we can call zap_remove() for the original string.
This should make no functional change, only a micro-optimization.
