There is a race in ME hardware between data copy for host and interrupt
delivery. An interrupt can be delivered prior to whole data copied for the
host to read but rather then going trough the reset we just merely need to
wait for the next interrupt.
The bug is visible in read/write stress with multiple connections per client
This is a regression caused as a side effect of the commit:
