[ Upstream commit 12ecbb4b1d765a5076920999298d9625439dbe58 ]
Commit e4502c63f56aeca88 (ufs: deal with nfsd/iget races) introduced
unlock_new_inode() call into ufs_add_nondir(). However that function
gets called also from ufs_link() which hands it already initialized
inode and thus unlock_new_inode() complains. The problem is harmless but
annoying.
Fix the problem by opencoding necessary stuff in ufs_link()
