of: fdt: add missing allocation-failure check

The memory allocator passed to __unflatten_device_tree() (e.g. a wrapped
kzalloc) can fail so add the missing sanity check to avoid dereferencing
a NULL pointer.

Fixes: 4d41df789678 ("of/flattree: Refactor unflatten_device_tree and add fdt_unflatten_tree")
