doDumpStates: incorrectly increments stats

doDumpStates calls stepInstruction and therefore indirectly increases time and
instruction statistics for all dangling (dumped) states. This patch removes the
call, but now the timing stats for the last executed state are lost, as
StatsTracker::stepInstruction isn't called anymore.
