Subject: [PATCH] app/testpmd: fix removed device link status asking

[ upstream commit 0da2a62bf9d72625fb5b779d9fd91e471ed2fb4a ]

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

Fixes: 284c908cc588 ("app/testpmd: request device removal interrupt")
