drm/i915: Guard against NULL driver_data in i915_pci_probe()
pci_match_device() can return the dummy pci_device_id_any entry
when a device is force-bound via sysfs driver_override, in which
case ->driver_data is unset (NULL). i915_pci_probe() casts it to
struct intel_device_info * unconditionally and dereferences
intel_info->require_force_probe, causing a NULL-ptr-deref.
