Merge tag 'nfsd-5.2-1' of git://linux-nfs.org/~bfields/linux

Pull nfsd fix from Bruce Fields:
 "This reverts a minor fix which could cause us to treat conflicting NLM
  locks as nonconflicting.

  We have proper fix queued up for 5.3. In the meantime, a quick revert
  seems best for 5.2 and stable"
