vdev_probe calls driver->probe and set dev->device.driver,
which will be NULL if the probe fails.
In vdev_cleanup, drv = container_of(dev->device.driver)
drv will be !NULL in this case, causing drv->remove
Segmentation fault.
Fixed by checking dev->device.driver before.
Log:
$ sudo dpdk-test --vdev=crypto_uadk --log-level=6
vdev_probe(): failed to initialize crypto_uadk device
EAL: Bus (vdev) probe failed.
RTE>>quit
Segmentation fault
