[dpdk-dev] [PATCH 07/12] cryptodev: release device if PCI device probing fails

[Pablo de Lara <pablo.de.lara.guarch@intel.com>]

Call rte_cryptodev_pmd_release_device() if probing a
PCI crypto device, instead of accessing the variables
directly. This will be useful when rte_cryptodev_pci_probe()
gets moved to a separate file.
