[Yaffs] ENAMETOOLONG not handled correctly

Hi,

I made this change and it seems to pass the Linux Test Project
tests:

chdir04
chroot03
creat06
mkdir03
nftw01
nftw6401
open08
rename10
statfs02

These tests involve making a file or directory that has too long
a name (ie. > 255).

Please tell me if you think my change is in error.

Thanks,

Rick Bronson
