lockd: posix_test_lock() should not call locks_copy_lock()
The caller of posix_test_lock() should never need to look at the lock private data, so do not copy that information. This also means that there is no need to call the fl_release_private methods. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
