NFS: Fix directory delegation verifier checks
Doing this check in nfs_check_verifier() resulted in many, many more
lookups on the wire when running Christoph's delegation benchmarking
script. After some experimentation, I found that we can treat directory
delegations exactly the same as having a delegated verifier when we
reach nfs4_lookup_revalidate() for the best performance.
