[Yaffs] An observation about "useHeaderFileSize" !

[Charles Manning]

The useHeaderFileSize option is only useful for YAFFS1.

YAFFS2 needs to use this otherwise various things break.
For this reason, yaffs_GutsInitialise forces this on for YAFFS2 in the th=
e=20
following lines:

if(dev->isYaffs2)=20
{
dev->useHeaderFileSize =3D 1;
}

Defeat this and YAFFS2 will break.
