Windows: Track active RPCs per scache_t
It has been noticed that multiple RPCs can be active on
a cm_scache_t object at the same time. This is especially
true of directory objects with the redirector. Track the
number of active RPCs and use that number in cm_MergeStatus
when deciding whether or not to discard the cached data for
the object.
