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
