Subject: nfsd: fix nfsdfs inode reference count leak

nfsd: fix nfsdfs inode reference count leak

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")
