NFS: Fix a sillyrename race...
Ensure that readdir revalidates its data cache after blocking on sillyrename. Also fix a typo in nfs_do_call_unlink(): swap the ^= for an |=. The result is the same, since we've already checked that the flag is unset, but it makes the code more readable. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
