[PATCH 5.7 073/112] nfsd: fix nfsdfs inode reference count leak

[ Upstream commit bf2654017e0268cc83dc88d56f0e67ff4406631d ]

I don't understand this code well, but I'm seeing a warning about a
still-referenced inode on unmount, and every other similar filesystem
does a dput() here.

Fixes: e8a79fb14f6b ("nfsd: add nfsd/clients directory")
