The patch fixes CFI issue with multipartitional devices leading to the 
set of errors or even deadlock. The problem is CFI FL_SYNCING state race 
with flash operations (e.g. erase suspend). It is reproduced by running 
intensive writes on one JFFS2 partition and simultaneously performing 
mount/unmount cycle on another partition of the same chip.
