[S390] qdio: continue polling for buffer state ERROR
Inbound traffic handling may hang if next buffer to check is in state ERROR, polling is stopped and the final check for further available inbound buffers disregards buffers in state ERROR. This patch includes state ERROR when checking availability of more inbound buffers.
