In read_handle(), of_get_address() may return NULL if getting address and size of the node failed. When of_read_number() uses prop to handle conversions between different byte orders, it could lead to a null pointer dereference. Add NULL check to fix potential issue.

Found by static analysis.

You need to describe the tool that found this. And how did you test that your fix is correct?
