That's harmless.  Flash is a write-once medium between erases.

Your setup appears sane in principle, so there must me a subtle
mistake you made (bugs are out of the question of course ;).  Missing
a real howto, let me run through the sequence:

1. Erase the flash partition.  Either
   o eraseall /dev/mtdX or
   o cat file_filled_with_0xff > /dev/mtdblockX

2. Do *not* write anything to it afterwards.  Jffs2 would just error
   out.

3. Mount jffs2.  Either
   o mount mtdX -t jffs2 <mount_point> or
   o mount /dev/mtdblockX -t jffs2 <mount_point>
