[Yaffs] yaffs kill_sb function and umount error

[Brad Beveridge]

I have also made this change in my yaffs tree.  Though the reason I made 
it was to support a removable nand device.  Without calling 
kill_block_super, the MTD block device system wouldn't rmmod cleanly. 
I posted here about the change & more details about my situation a few 
weeks ago.
