Tweaked the patch a bit to make sure 'init_constants_master()' is called
before we start fixing-up - this does not matter now but it is less
error prone. And pushed to the UBIFS git tree, thank you.

But please, do review my tweaks and test them. When you confirm it
works, I'll send a pull request to Linus.
