Description

eth/handler: remove duplicate check for lists in body

Rationale

in this PR(#2461),
check for 3 lists Uncles, Transactions, Withdrawals is added.

but indeed, most of them are useless, because
if block recieved by handleBlockBodies,
Uncles and Transactions have been checked at https://github.com/bnb-chain/bsc/blob/master/eth/fetcher/block_fetcher.go#L718
if block recieved by handleNewBlock
Uncles and Transactions have been checked at https://github.com/bnb-chain/bsc/blob/master/eth/protocols/eth/handlers.go#L316
so only add check for Withdrawals` is ok.

the check for Transactions cost not a little time when block is huge,
by removing the dupicate check, a better performance can be acheived

so this PR have 2 commits,
the first one is to revert the above PR,
the second one add the check for Withdrawals`

Example

add an example CLI or API response...
