[S390] qdio: report SIGA errors directly
Errors from SIGA instructions are stored in the per queue qdio_error and reported back when the queue handler is called. That opens a race when multiple error conditions occur simultanously. Report SIGA errors immediately in the return value of do_QDIO so the upper layer can react and SIGA errors no longer interfere with other errors. Move the SIGA error handling in qeth from the outbound handler to qeth_flush_buffers. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com>
