nfsd4: use a single struct file for delegations
When we converted to sharing struct filess between nfs4 opens I went too
far and also used the same mechanism for delegations. But keeping
a reference to the struct file ensures it will outlast the lease, and
allows us to remove the lease with the same file as we added it.
