nfsd: fix refcount leak when file is unhashed after being found

Browse Source 
[ Upstream commit 8a79261763 ]

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.

Fixes: c6593366c0 ("nfsd: don't kill nfsd_files because of lease break error")
