[S390] qdio: fix error reporting for hipersockets
Hipersocket connections can encounter temporary busy conditions. In case of the busy bit set we retry the SIGA operation immediatelly. If the busy condition still persists after 100 ms we fail and report the error to the upper layer. The second stage retry logic is removed. In case of ongoing busy conditions the upper layer needs to reset the connection. The reporting of a SIGA error is now done synchronously to allow the network driver to requeue the buffers. Also no error trace is created for the temporary SIGA errors so the error message view is not flooded.
