of: Fix missing memory initialization on FDT unflattening
Any calls to dt_alloc() need to be zeroed. This is a temporary fix, but the allocation function itself needs to zero memory before returning it. This is a follow up to patch 9e4012752, "of: fdt: fix memory initialization for expanded DT" which fixed one call site but missed another.
