[dpdk-dev] [PATCH] bus/vdev: fix uninitialized device bus

Device bus should be initialized after bus scan.
While it does not happened when scan vdev from secondary process,
that cause segment fault at rte_dev_probe when call dev->bus->xxx.

Fixes: cdb068f031c6 ("bus/vdev: scan by multi-process channel")
