[PATCH v1 1/2] bus/vdev: fix memory leak

[Wenjun Wu]

In hotplug usecase, devargs will be allocated in secondary process
in the function alloc_devargs. Since it will not be insert into the
devarg_list, it will have no chance to be freed.

This patch adds additional memory free for device structure member devargs
in the secondary process in rte_vdev_uninit.
