[dpdk-dev] [PATCH] ethdev: fix device state on close

[Shahaf Shuler <shahafs@mellanox.com>]

Currently device state moves between ATTACHED when device was
successfully probed to UNUSED when device is detached or released.

The device state following rte_eth_dev_close() operation is inconsist,
The device is still in ATTACHED state, however it cannot be used
in any way till it will be probed again.

Fixing it by changing the state to UNUSED.
