Re: dtc: Fix uninitialized use of structure_ok

So, like, the other day David Gibson mumbled:

My rework of the tree checking code introduced a potentially nasty bug
- it uses the structure_ok variable uninitialized.  This patch fixes
the problem.  It's a fairly ugly bandaid approach, but the ugly will
disappear once future patches have folded the semantic checks into the
new framework.

Applied.

Thanks!
