PROBLEM: (93344, 92012) (PATCH ID: OSF445-451)
********
This patch corrects two issues:
A race condition exists where map entries can go away within the map while it is
being traversed.  This causes a KMF when a NULL pointer is dereferenced.

The ioctl PIOCMAP uses a previously computed count for how many map entries
to retrieve. But the number of entries could have changed since that count was
retrieved. This fix makes sure that if the number of entries has decreased, the
code will not walk off the end of the list and panic.
