afs: Improve server refcount/active count tracing

Browse Source 
Improve server refcount/active count tracing to distinguish between simply
getting/putting a ref and using/unusing the server record (which changes
the activity count as well as the refcount).  This makes it a bit easier to
work out what's going on.
