nfsd: remove unnecessary positive-dentry check
vfs_{create,mkdir,mknod} each begin with a call to may_create(), which returns EEXIST if the object already exists. This check is therefore unnecessary. (In the NFSv2 case, nfsd_proc_create also has such a check. Contrary to RFC 1094, our code seems to believe that a CREATE of an existing file should succeed. I'm leaving that behavior alone.)
