Correctly close old nfsd/lockd sockets.
Commit aaf68cfbf2241d24d46583423f6bff5c47e088b3 added a bias to sk_inuse, so this test for an unused socket now fails. So no sockets get closed because they are old (they might get closed if the client closed them). This bug has existed since 2.6.21-rc1. Thanks to Wolfgang Walter for finding and reporting the bug.
