  -----------
  [coro] Correct CurrentBlock tracking bug recently introduced

We use the CurrentBlock to determine whether we have already processed a
block. Don't reuse this variable for setting where we should insert the
rematerialization. The rematerialization block is different to the
current block when we rematerialize for coro suspend block users.
