Zilin Guan 235a1eb8d2 of: unittest: Fix memory leak in unittest_data_add() ...

In unittest_data_add(), if of_resolve_phandles() fails, the allocated
unittest_data is not freed, leading to a memory leak.

Fix this by using scope-based cleanup helper __free(kfree) for automatic
resource cleanup. This ensures unittest_data is automatically freed when
it goes out of scope in error paths.

For the success path, use retain_and_null_ptr() to transfer ownership
of the memory to the device tree and prevent double freeing.
