The vdev_probe calls driver->probe, which may fail
and dev->device.driver will still be NULL.
In vdev_cleanup, drv = container_of(dev->device.driver) returns !NULL,
then drv->remove will trigger Segmentation fault.
Fix it by checking dev->device.driver first.
Log:
Thread 1 "dpdk-test" received signal SIGSEGV, Segmentation fault.
