nfsd: fix refcount leak when file is unhashed after being found
[ Upstream commit 8a7926176378460e0d91e02b03f0ff20a8709a60 ]
If we wait_for_construction and find that the file is no longer hashed,
and we're going to retry the open, the old nfsd_file reference is
currently leaked. Put the reference before retrying.
