[dpdk-dev] [PATCH 1/3] ethdev: avoid error on PCI unplug of already closed ethdev

[Andrew Rybchenko]

If PCI Ethernet device driver removes it on close
(RTE_ETH_DEV_CLOSE_REMOVE) and later PCI device itself is unplugged,
it should not fail because of Ethernet device is already removed.

Fixes: 23ea57a2a0ce ("ethdev: complete closing of port")
