[dpdk-dev] [PATCH 02/20] ethdev: allow drivers to return error on close

[Thomas Monjalon]

The device operation .dev_close was returning void.
This driver interface is changed to return an int.

Note that the API rte_eth_dev_close() is still returning void,
although a deprecation notice is pending to change it as well.
