Trond Myklebust 10717f4563 NFSv4: Limit the total number of cached delegations 
Delegations can be expensive to return, and can cause scalability issues
for the server. Let's therefore try to limit the number of inactive
delegations we hold.
Once the number of delegations is above a certain threshold, start
to return them on close.
