[PATCH] md: make sure the events count in an md array never returns to zero
Now that we sometimes step the array events count backwards (when
transitioning dirty->clean where nothing else interesting has happened - so
that we don't need to write to spares all the time), it is possible for the
event count to return to zero, which is potentially confusing and triggers and
MD_BUG.
We could possibly remove the MD_BUG, but is just as easy, and probably safer,
to make sure we never return to zero.
