[dpdk-dev] [PATCH 5/6] app/testpmd: fix removed device link status asking

[Matan Azrad <matan@mellanox.com>]

In the RMV device event callback, there is a call for the removed
device stop operation which trigers a link status operation for the
removed device.

It may casue an error from the removed device PMD.

Skip the link status operation in the above described case.
