[PATCH]fs/jffs2/wbuf.c: add compatibility support for OOB data block

[Ferenc Havasi]

Hi Artem,

We tried the latest snapshot with summary and without summary and it 
reported CRC errors. We tried it with older JFFS2 snapshot and it worked 
well.

Our plan was - even if Jörn and David say our patch is OK -, to wait 
commiting our patch to keep the picture clear, and try to help you to 
find the bug in your improvements (which has a nice result). But 
becuseof our and your holidays it may will be later...

Bye,
Ferenc
