To convert option to error we generate an error message. In some places
it contains header or block hash code or other data which is costly to
produce. So during the initial header sync we spend 12% of all time on
generating those messages (in 99% cases we don't use it). This PR
introduces a lazy generation of error messages which completely
eliminates CPU load during the header sync.

* Fix locking bug when calling is_on_current_chain() in batch.blocks_iter just by removing it.
Because "we want to delete block older (i.e. lower height) than tail.height".
