[PATCH]jffs2 fix for dataflash + odd erasesizes

[Peter Menzebach]

This patch fixes jffs2 for use with atmel dataflash. Now every part of 
jffs2 should be able to handle erase sizes and wbuf sizes, which are not 
2^X.

The patch has some trivial changes, where erase sizes were relying on a 
size of 2^X. The rest of the changes in wbuf.c does affect only 
dataflash handling.
