private-tx: replace error_chain (#10510)

* Update to vanilla tx pool error

* private-tx: remove error-chain, implement Error, derive Display

* private-tx: replace ErrorKind and bail!

* private-tx: add missing From impls and other compiler errors

* private-tx: use original tx-pool error

* Don't be silly cargo
