Revert "replay: stop us hanging in rr_wait_io_event"
This reverts commit 1f881ea4a444ef36a8b6907b0b82be4b3af253a2.
That commit causes reverse_debugging.py test failures, and does
not seem to solve the root cause of the problem x86-64 still
hangs in record/replay tests.
The problem with short-cutting the iowait that was taken during
record phase is that related events will not get consumed at the
same points (e.g., reading the clock).
A hang with zero icount always seems to be a symptom of an earlier
problem that has caused the recording to become out of synch with
the execution and consumption of events by replay.
