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.
