[PATCH] md: possible fix for unplug problem

I have reports of a problem with raid5 which turns out to be because the raid5
device gets stuck in a 'plugged' state.  This shouldn't be able to happen as
3msec after it gets plugged it should get unplugged.  However it happens
none-the-less.  This patch fixes the problem and is a reasonable thing to do,
though it might hurt performance slightly in some cases.

Until I can find the real problem, we should probably have this workaround in
place.
