    selftests/xsk: print correct error codes when exiting
    
    [ Upstream commit 085dcccfb7d3dc52ed708fc588587f319541bc83 ]
    
    Print the correct error codes when exiting the test suite due to some
    terminal error. Some of these had a switched sign and some of them
    printed zero instead of errno.
