[PATCH] ubifs: remove wrong assertion

[Sascha Hauer]

In barebox copy_znode() doesn't make a copy of the znode, We are limited
to readonly support, so copy_znode() returns the original node.
tnc_delete() expects a znode to be dirty and has an assertion for this.
In a normal r/w implementation this is correct, but not in barebox, so
drop the assertion. Instead of removing it just comment it out to make
sure it won't be added again with the next ubifs kernel synchronisation.
