s390/qdio: improve handling of PENDING buffers for QEBSM devices
For QEBSM devices the 'merge_pending' mechanism in get_buf_states() doesn't apply, and we can actually get SLSB_P_OUTPUT_PENDING returned. So for this case propagating the PENDING state to the driver via the queue's sbal_state doesn't make sense and creates unnecessary overhead. Instead introduce a new QDIO_ERROR_* flag that gets passed to the driver, and triggers the same processing as if the buffers were flagged as QDIO_OUTBUF_STATE_FLAG_PENDING.
