v2:
- use nfsd_lookup_dentry instead of lookup_one_len

Here's a respin of the patches to fix up the potential race between an
open and delegation. I took Neil's advice an changed over to use
nfsd_lookup_dentry.

This patchset is based on top of Neil's recent patchset entitled:

    [PATCH 0/8] NFSD: clean up locking.

Tested with xfstests and it seemed to behave. I haven't done any testing
to ensure that the race is actually fixed, mainly because I don't have a
way to reliably reproduce it.

  nfsd: drop fh argument from alloc_init_deleg
  nfsd: vet the opened dentry after setting a delegation
