Subject: [PATCH] of: Fix missing memory initialization on FDT unflattening

commit 0640332e073be9207f0784df43595c0c39716e42 upstream.

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.
