Dave Collins a4a52ae24f wire: Remove errs from BlockHeader/MsgBlock/MsgTx.
This commit removes the error returns from the BlockHeader.BlockSha,
MsgBlock.BlockSha, and MsgTx.TxSha functions since they can never fail and
end up causing a lot of unneeded error checking throughout the code base.

It also updates all call sites for the change.
