Re: libfdt: Fix use of uninitialized variable in fdt_get_path()

So, like, the other day David Gibson mumbled:

My recent implemenetation of fdt_get_path() had a bug - the while loop
tested offset which was unitialized on the first iteration.  Depending
on code surrounding the call, this could cause fdt_get_path() to
return incorrect results.

This patch corrects the problem by applying some more correct thinking
to the loop condition.

Applied.
