core: allow early Seek stop This simple approach allows to improve the performance of BoltDB and LevelDB in both terms of speed and allocations for retrieving GasPerVote value from the storage. MemoryPS's speed suffers a bit, but we don't use it for production environment. Part of #2322.

core: allow early Seek stop This simple approach allows to improve the performance of BoltDB and LevelDB in both terms of speed and allocations for retrieving GasPerVote value from the storage. MemoryPS's speed suffers a bit, but we don't use it for production environment. Part of #2322.
