Try if tombstone is eligable for pruning before locking on it's key ()
Pruning tombstones is quite expensive since we have to walk though all
deletes in the live version map and acquire a lock on every value even though
it's impossible to prune it. This change does a pre-check if a delete is old enough
and if not it skips acquireing the lock.
