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.)
