[JFFS2] Remove flash offset argument from various functions.
Browse files Browse the repository at this point in the history 
We don't need the upper layers to deal with the physical offset. It's
_always_ c->nextblock->offset + c->sector_size - c->nextblock->free_size
so we might as well just let the actual write functions deal with that.
