[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.
