Removed a bit of unneeded code in the Wood PPipe

@King_Lemming this will break compat with RS Cells because you're doing
it wrong. Don't use powerRequest() like that and don't ignore the return
of receiveEnergy().

PS. It was already broken because the cell was just throwing power away
because it was ignoring the return of receiveEnergy().
