[dpdk-dev] [PATCH 1/2] bus/pci: Fail rte_pci_probe if probing all whitelisted devices fail.

[Nitin Katiyar <nitin.katiyar@ericsson.com>]

Even if whitelist of devices is provided, rte_pci_probe() increments
the probed counter for all the devices present in the system. If probe
fails for all the whitelisted devices it still return success because
failed and probed counts don't match.

This patch increments probed count only when devices are actually
probed.
