device-display: Add hal_backend_device_display_funcs initialization

When the hal module fails open hal-backend,
after free hal_backend_[module]_funcs structure, it should be initialized by NULL.
Otherwise, there will be an error when approaching above function pointer structure.
To avoid accessing uninitialized value, this is necessary.
